Remove call to fetch_os_creds.sh

After [1], the openstack credentials
are provided to Functest as a volume
directly from CI. The same has to be
done manually.
Functest doesn't need the script
fetch_os_creds.sh any longer.

 Accessing the Openstack credentials
 -----------------------------------
-OpenStack credentials are mandatory and can be retrieved in different
-ways. From inside the running Functest docker container the
-"functest env prepare" command will automatically look for the
-Openstack credentials file "/home/opnfv/functest/conf/openstack.creds"
-and retrieve it unless the file already exists. This Functest
-environment preparation step is described later in this document.
-
-WARNING: When the installer type is "joid" you have to have the
-credentials file inside the running container **before** initiating the
-functest environment preparation. For that reason you have to choose
-either one of the options below, since the automated copying does not
-work for "joid".
-
-You can also specifically pass in the needed file prior to running the
-environment preparation either:
-
-  * by using the -v option when creating the Docker container. This is
-    referred to in docker documentation as "Bind Mounting". See the
-    usage of this parameter in the following chapter.
-  * or creating a local file '/home/opnfv/functest/conf/openstack.creds'
-    inside the running container with the credentials in it. Consult
+OpenStack credentials are mandatory and must be provided to Functest.
+When running the command "functest env prepare", the framework  will
+automatically look for the Openstack credentials file
+"/home/opnfv/functest/conf/openstack.creds" and will exit with
+error if it is not present or it is empty.
+
+There are 2 ways to provide that file:
+
+  * by using a Docker volume with -v option when creating the Docker container.
+    This is referred to in docker documentation as "Bind Mounting".
+    See the usage of this parameter in the following chapter.
+  * or creating manually the file '/home/opnfv/functest/conf/openstack.creds'
+    inside the running container and pasting the credentials in it. Consult
     your installer guide for further details. This is however not
     instructed in this document.
 
-NOTE: When the installer type is "fuel" and virtualized deployment
-is used, there you have to explicitly fetch the credentials file
-executing the following sequence
-
-  #. Create a container as described in next chapter but do not
-     "Bind Mount" the credentials
-  #. Log in to container and execute the following command. Replace
-     the IP with installer address after the "-a" parameter::
-
-       fetch_os_creds.sh \
-       -d /home/opnfv/functest/conf/openstack.creds \
-       -i fuel \
-       -a 10.20.0.2 \
-       -v
-       ( -d specifies the full path to the Openstack credential file
-       -i specifies the INSTALLER_TYPE
-       -a specifies the INSTALLER_IP
-       -v indicates a virtualized environment and takes no arguments )
-
-  #. Continue with your testing, initiate functest environment
-     preparation, run tests etc.
+There is a default environment variable in the Functest container **$creds**
+that points to the credentials absolute path to help the user with this task.
 
 In proxified environment you may need to change the credentials file.
