python: Remove init_lockspace() deprecated API
write_lockspace() is used to replace init_lockspace() functionality
as far back as in commit:
commit 3e17957

python: use the write commands in example.py
The init_lockspace/resource commands have been obsoleted, the new ones
are write_lockspace/resource.
The old API was kept to support legacy python2-sanlock consuming code.
Now that python2 is officialy retired this API can be removed.
