Implement initial clover-controller service

- First pass of clover-controller which resides within the k8s
cluster and provides interfaces to all Clover services
- Only service that should need to be exposed outside of
cluster
- Docker build of container that uses stack of nginx, gunicorn
and flask to provide REST interface
- REST interface is intended to serve cloverctl CLI and
dashboard browser UI
- Implements GRPC messaging to clover-collector and snort
- GRPC interfaces files for snort/nginx are added to
container from repo. Collector GRPC files will be removed
from controller/control/api once patch below is merged
https://gerrit.opnfv.org/gerrit/#/c/57245/ and added
similarly
- Provides first pass callback for file upload from
clover-server.
- Some REST messages implement JSON for passing params
to internal services
- Redis interface added to obtain data from services.
Currently, a simple interface to retrieve snort event
information
- YAML manifest renderer to add to k8s. Uses NodePort
service currently, defaulting to port 32044.

- Removed collector gRPC interface files with merge of collector
- Expose tracing and monitoring host/port parameters, as these vary
depending on Istio version and Jaeger version
- Add logging to flask blueprints
- Added jmeter blueprint interface with REST for
testplan generation, start test and result retrieval
- Added flask Response to REST reply messages
- Retrieve some basic stats from collector in json
response
