"sql_connection = ://:@/" is left when database relation is not ready

[Nobuto Murata]

parts/database is not conditioned by "{% if database_host -%}". So "sql_connection = ://:@/" will be left in nova.conf when database relation is not ready.

> sql_connection = {{ database_type }}://{{ database_user }}:{{ database_password }}@{{ database_host }}/{{ database }}{% if database_ssl_ca %}?ssl_ca={{ database_ssl_ca }}{% if database_ssl_cert %}&ssl_cert={{ database_ssl_cert }}&ssl_key={{ database_ssl_key }}{% endif %}{% endif %}

Also is it necessary to have database access from nova-api-metadata? I can get metadata without database relation.

I think that you are probably correct - metadata is probably retrieved using RPC + the nova conductor.

I have tested it. the sql_connection isn't necessary indeed. will upload a patch later.
