ceilometer client is a rare client that doesn't allow to use a keystoneclient/keystoneauth session object. This change fixes that and will allow to remove the deprecated apiclient code in the future. Depends-On: I43223a8b38ff1f4ef30c1d2345a28de6ade51863 Depends-On: I7cbe0afa12c9d11ce2eaed1f4d29f41507e273f8 Change-Id: I4804c45c2ba69982163503ba5d9d4eba86f904fe
