Allow definition of lock mode for custom reloptions

Browse Source 
Relation options can define a lock mode other than AccessExclusiveMode
since 47167b7, but modules defining custom relation options did not
really have a way to enforce that.  Correct that by extending the
current API set so as modules can define a custom lock mode.
