Danube Release Docs Fixup patch 1

Done in this patch
1. Fixes in overview.rst
2. Moves governance folder under docs
3. Adds arno release use case doc from
https://wiki.opnfv.org/display/parser/Parser+Use+Cases to the
requirement folder
4. Moves two old tosca2heat documents into developer/design/examples
5. Adds new empty tosca2heat and verigraph design document under
developer/design.
6. Remove old contents in yang2tosca and policy2tosca design docs since
they are all related to installation/execution, not design.
7. Fixes in installation.instruction.rst and usage,guide.rst

To do in the following patches
1. Design doc writeup: Xiaodong(tosca2heat),
Shiva(yang2tosca/policy2tosca), Serena(verigraph)

+Parser polic2tosca
 ===================
 
-Overview
-========
 
-Parser is an open source project and licensed under Apache 2. Parser will help
-to provide a tooling mechanism, by parsing Telecom operators’ VNF descriptors
-(YANG templates) into TOSCA templates and then further translate TOSCA
-templates into certain common templates, which could be used in IaaS orchestration
-projects like OpenStack Heat.
-
-Prerequisites
-=============
-
-Parser - POLICY2TOSCA requires the following to be installed.
-
-1. cliff
---------
-
-Install cliff with the following links.
-::
-- `install <http://docs.openstack.org/developer/cliff/install.html>`
-or
-- `demoapp <http://docs.openstack.org/developer/cliff/demoapp.html>`
-
-Installation
-============================
-
-Please follow the below installation steps to install parser - POLICY2TOSCA.
-
-Step 1: Clone the parser project.
-
-.. code-block:: bash
-
-    git clone https://gerrit.opnfv.org/gerrit/parser
-
-Step 2: Install the policy2tosca module.
-
-.. code-block:: bash
-
-    cd parser/policy2tosca
-    python setup.py install
-
-Execution
-===========================
-
-Step 1: To see a list of commands available.
-
-.. code-block:: bash
-
-    policy2tosca --help
-
-Step 2: To see help for an individual command, include the command name on the command line
-
-.. code-block:: bash
-
-    policy2tosca help <service>
-
-Step 3: To inject/remove policy types/policy definitions provide the TOSCA file as input to policy2tosca command line.
-
-.. code-block:: bash
-
-    policy2tosca <service> [arguments]
-
-Example:
-
-.. code-block:: bash
-
-    policy2tosca add-definition --policy_name rule2 --policy_type  tosca.policies.Placement.Geolocation --description "test description" --properties region:us-north-1,region:us-north-2,min_inst:2 --targets VNF2,VNF4 --metadata "map of strings" --triggers "1,2,3,4" --source example.yaml
-
-
-Step 4: Verify the TOSCA YAMl updated with the injection/removal executed.
-
-.. code-block:: bash
-
-    cat "<source tosca file>"
-
-Example:
-
-.. code-block:: bash
-
-    cat example_tosca.yaml

+ 
+Hi everyone, 
+  
+Since I received only one comment from Julien so far on the cap of committer number, I updated the slide to address Juline’s comment and call for your approval. Please reply +1 if you are ok with our non-mandatory additional guideline, or specify your concerns if you have doubts about the current version. 
+  
+As I discussed in the previous meetings, after the slide (i.e the “Motion”) got unanimous +1 approval, I will submit it to our Parser repo so that it becomes a public document. Any further changes to the document should be done in a similar way: PTL or committer initiate a motion via email, and after committer approval submit it to parser repo, and merge after all the concerns addressed (all the -1 comments) 
+  
+This first document will be merged after the consent from you guys tho, since this is the starting piece. 
+  
+I will also show the record of the committer voting for openness and publicity. 
+  
+

+============================================
+Parser Project Committer Promotion Guideline
+============================================
+
+Note
+====
+
+This rst document serves only as a guideline for current committers and PTL to
+refer when they are electing new committers. We would strongly recommend the
+qualities listed in this document (in the Guidelines section) to be taken into
+consideration, however there is no legal or mandatory authority whatsoever.
+Any terms that might be in conflict with TSC charter is void by nature.
+
+Goal
+====
+
+* Make Parser grow stronger and healthier, with more new ideas and new
+  contributors.
+* Few committers who work with more contributors on a large size of work.
+* Committers number expands when Parser project itself grows.
+* Committer swap to ensure participating company’s interest.
+* Do not mandatory set limit to ban contributors to run, the ultimate result of
+  a promotion is still a consensus driven by community discussion.
+
+Rationale
+=========
+
+* Committers should be a small group of core contributors that could provide
+  a leading force for a balk of work in the project.
+* As a small new project, the growth of Parser is very important.
+* For any newly proposed committers, besides KPIs like commits, they should be
+  able to bring and work on an appropriate size of workload, with or without new
+  work force, so that the ratio between committer numbers and the workload is
+  appropriate.
+* Key mission of the committer is to expand and strengthen the project,
+  with new ideas or new participants.
+
+Guidelines
+==========
+
+* For those who are proposed as committers, if other KPI holds, for approval
+  they should have new work plan proposed that are beyond the work from past
+  release. For those who have brought forward both new work plan as well as
+  new contributors, their promotion should be considered approved in a fast
+  track.
+* For those who are proposed as committers, if other KPI holds, but they only
+  cover a similar size of work to the past release, for approval they should
+  replace the original committer of the same company. If there is no previous
+  committer member from the same company, then the promotion should be put
+  through with enough discussions.
+* There will be a cap on committer number per company. It is recommended that
+  each participating should not have more than 2 committers at the moment.
+  However this cap subjects to modification in the future should the team
+  decide to change. There is no cap for individual contributors.
+
+Guideline Creation and Modification Procedure
+=============================================
+
+* Current committers vote on this motion via email, approval require a unanimous
+  consent.
+* Submit this motion as a rst file into the parser governance repo, to setup a
+  precedent. PTL should kick off a review for the document each cycle.
+* Any future change to the guideline should be done via new patches and code
+  reviews, with record of showing a previous committer unanimous vote result on
+  the motion of such modification.
