convert restart_required to 'true' or 'false' string

The output of the configuration-parameters-list/show was
inadvertently changed when the parameters were moved into
the database in Juno.

Closes-Bug: #1379665
restart_required cfg-param is bool and not string

There was a break to the previous version of the configuration
paramenters API when the configurations parameters were moved to
the database. The actual type of the restart_required parameter
should be a JSON boolean value, and not a string to be compatible
with the previous configuration parameters API.

cluster_config argument missing in prepare()

Due to a bad merge, the prepare() call in postgresql does
not have cluster_config argument. Added that to make sure
postgres is in line with other data stores.
