glusterd: Better op-version values and ranges
Till now, the op-version was an incrementing integer that was incremented by 1 for every Y release (when using the X.Y.Z release numbering). This is not flexible enough to handle backports of features into Z releases. Going forward, from the upcoming 3.6.0 release, the op-versions will be multi-digit integer values composed of the version numbers, instead of a simple incrementing integer. An X.Y.Z release will have XYZ as its op-version. Y and Z will always be 2 digits wide and will be padded with 0 if required. This way of bumping op-versions allows for gaps in between the subsequent Y releases. These gaps will allow backporting features from new Y releases into old Z releases.
