build: Introducing python-gluster package

Currently the gluster namespace/module is owned by glusterfs-api rpm.
Because of this, other packages (extra-xlators or libgfapi-python)
have to depend on glusterfs-api to get the gluster namespace. The gluster
namespace should be owned by a core package.This patch introduce new package
called python-gluster and moves the ownership of gluster module
to python-gluster.

+GlusterFS is a distributed file-system capable of scaling to several
+petabytes. It aggregates various storage bricks over Infiniband RDMA
+or TCP/IP interconnect into one large parallel network file
+system. GlusterFS is one of the most sophisticated file systems in
+terms of features and extensibility.  It borrows a powerful concept
+called Translators from GNU Hurd kernel. Much of the code in GlusterFS
+is in user space and easily manageable.
+
+This package contains the python modules of GlusterFS and own gluster
+namespace.
