LU-15451 sec: read-only nodemap flag

Add a new 'readonly_mount' property to nodemaps. When set, we return
-EROFS from server side if the client is not mounting read-only.
So the client will have to specify the read-only mount option to be
allowed to mount.

Fixes: 928714dddabb ("LU-5092 nodemap: save id maps to targets in new index file")
