Fix db sync relationships

The tuskar puppet module doesn't specify a 'tuskar' package (or
title), the package declaration is managed by generic_service define,
and the package title is generated using service name (eg. 'api') and
the prefix 'tuskar-', so let's switch to 'tuskar-api' for package
dependency.

The tuskar puppet module doesn't specify a 'tuskar' user, let's remove
this relationship.

And finally this patch fix the relationship about 'database/connection'
it's 'database/sql_connection' in this module, and use tuskar_config
instead of Keystone_config.
