The nova_proxy_* options are not needed when Trove single tenant
functionnality is not used.
The current way how Kolla configure trove-taskmanager.conf is to use the
user tenant so the nova_proxy_* options are not required by default.
I added the "enable_trove_singletenant" option to enable the single tenant
functionnality if required and complete the configuration to make it works.
When enable_trove_singletenant is true, the below configuration will be
applied to trove-task-manager.conf configuration file:
nova_proxy_admin_pass = {{ trove_keystone_password }}
nova_proxy_admin_tenant_name = services
nova_proxy_admin_user = trove
remote_nova_client = \
trove.common.single_tenant_remote.nova_client_trove_admin
remote_cinder_client = \
trove.common.single_tenant_remote.cinder_client_trove_admin
remote_neutron_client = \
trove.common.single_tenant_remote.neutron_client_trove_admin
