This patch fixes following issues:
1. The existing envvar DATA_SOURCE_NAME overrides the setting specified
in the mysql_user.cnf file, ignore setting placed there;
2. Version 0.10 of the exporter does not support TLS, moving this to
minimally 0.11; and
3. Changed the host to the internal long name rather than the short
name.
