New xlator option to control enable/disable of xlators in Gd2

Browse Source 
Since glusterd2 don't maintain the xlator option details in code, it
directly reads the xlators options table from `*.so` files. To support
enable and disable of xlator new option added to the option table with
the name same as xlator name itself.

This change will not affect the functionality with glusterd1.
