server/auth: add option for strict authentication

When this option is enabled, we will check for a matching
username and password, if not found then the connection will
be rejected. This also does a checksum validation of volfile

The option is invalid when SSL/TLS is in use, at which point
the SSL/TLS certificate user name is used to validate and
hence authorize the right user. This expects TLS allow rules
to be setup correctly rather than the default *.

This option is not settable, as a result this cannot be enabled
for volumes using the CLI. This is used with the shared storage
volume, to restrict access to the same in non-SSL/TLS environments
to the gluster peers only.

Tested:
  ./tests/bugs/protocol/bug-1321578.t
  ./tests/features/ssl-authz.t
  - Ran tests on volumes with and without strict auth
    checking (as brick vol file needed to be edited to test,
    or rather to enable the option)
  - Ran tests on volumes to ensure existing mounts are
    disconnected when we enable strict checking
