zhurong df7ecbc290 Fix client could not init glance client
Now the client can not initialise glance client,
give the warning msg like:
# murano environment-create test-env
Could not initialise glance client. Image creation will be unavailable.

Have two issue about this:
1. can not get the endpoint correctly, the get endpoint
are all murano's endpoint. This is due to when get the endpoint, if have
the endpoint, will return this endpoint directly.
2. Get the correctly endpoint, init the glance client, give the error:
TypeError: "__init__() got an unexpected keyword argument 'endpoint_type'"
This is due to 'endpoint_type' argument.
