rpc: implement server.manage-gids for group resolving on the bricks
The new volume option 'server.manage-gids' can be enabled in environments where a user belongs to more than the current absolute maximum of 93 groups. This option triggers the following behavior: 1. The AUTH_GLUSTERFS structure sent by GlusterFS clients (fuse, nfs or libgfapi) will contain only one (1) auxiliary group, instead of a full list. This reduces network usage and prevents problems in encoding the AUTH_GLUSTERFS structure which should fit in 400 bytes. 2. The single group in the RPC Calls received by the server is replaced by resolving the groups server-side. Permission checks and similar in lower xlators are applied against the full list of groups where the user belongs to, and not the single auxiliary group that the client sent.
