Code Issues Proposed changes

Allow DATABASE_TYPE to be specified in localrc

Browse Source 
The use of DATABASE_TYPE without forcing it into ENABLED_SERVICES
seems to be the only way to set up a multi-host devstack installation.

Only deprecate use_database.
Changes functionality of use_database to be equivalent to specifying DATABASE_TYPE
This means that people with localrc's that only specify use_database used to have
a database service brought up, but now will not until they add it to ENABLED_SERVICES.
