Do not require every script that sources stackrc to also source lib/databases. * Move use_databases() to functions * Set DATABASE_TYPE in stackrc * Allow setting DATABASE_TYPE in localrc to work (use_database() essentially just sets DATABASE_TYPE at this stage so continuing to use it is equivalent) * Validate DATABASE_TYPE in stack.sh. * Change sudo to postgresql user to go through root to eliminate password prompt * fix use_database error condition Change-Id: Ibb080c76e6cd7c6eebbb641a894d54b1dde78ca6
