[murano] [murano-cfapi] error while creating cf service broker

[Alex Kholkin]

Bug description:
Currently it is not possible to create murano service broker via cf api because 'Using keystoneclient sessions has been deprecated. Please update your software to use keystoneauth1.'

Steps to reproduce:
1. deploy last devstack with murano and enable_service murano-cfapi
2. deploy cf
3. ssh to the instance
4. Register client with "cf api api.system.cloudfoundry --skip-ssl-validation", where api.system.cloudfoudry mapped to cf host (via DNS or Hosts file)
5. exec 'cf login'
6. try to register service-broker in cloud foundry via 'сf create-service-broker murano admin admin <url>' , url = http://172.18.92.101:8083/, for example.

Expected result:
service broker is created

Actual result:
`Creating service broker murano as admin...
FAILED
Server error, status code: 502, error code: 270012, message: Service broker catalog is invalid:
Service broker must provide at least one service
`

The in-process cache causes inconsistent results and high memory usage. When the feature is removed the auth_token middleware will not cache tokens by default which may result in performance issues. It is recommended to use memcache for the auth_token token cache by setting the memcached_servers option.
