This option allow migration to a non compression server config while
still retraining compatibility with client that have a compression
setting in their config.
For existing setups that used to have comp-lzo no or another
compression setting in their configs it is a difficult to migrate to
a setup without compression without replacing all client configs at
once especially if OpenVPN 2.3 or earlier clients are in the mix that
do not support pushing stub-v2. Even with OpenVPN 2.4 and later clients
that support pushing this is not a satisfying solution as the clients
log occ mismatches and the "push stub-v2" needs to be in the server
config "forever".
If the new migrate option to compress is set and a client is detected
that indicates that compression is used (via OCC), the server will
automatically add ``--push compress stub-v2`` to the client specific
configuration if stub-v2 is supported by the client and otherwise
switch to ``comp-lzo no`` and add ``--push comp-lzo`` to the client
specific configuration.
Patch v2: better commit message/man page, add USE_COMP ifdefs, various
style fixes
