glusterd: Get maximum supported op-version in a cluster
gluster volume get <VOLNAME> cluster.opversion gives us the current op-version on which the cluster is operating. There is no command that lets the user know the maximum supported op-version that the cluster can run on. This patch adds a new global option cluster.max-op-version, that can be used to retrieve the maximum supported op-version in a cluster. Usage: # gluster volume get all cluster.max-op-version Example output: Option Value ------ ----- cluster.max-op-version 30900 NOTE: The only way to test this feature for now is to set the GD_OP_VERSION_MAX macro to different values (30800 for 3.8,30900 for 3.9, and so on) and rebuild glusterd. Since the regression test framework currently doesn't have support to simulate these tests, there are no accompanying regression tests for this feature. It should be possible to add tests once glusto comes in and makes it easier to run a heterogeneous cluster.
