If there is per-node data then each chunk is read in a separate call

is confusing.
Instead, a single call now reads all data for multiple nodes and

This simply calls out to the wrapper, so that commands are changed as
follows:
ctdb lvsmaster -> ctdb lvs master
ctdb lvs -> ctdb lvs list
This provides a simple, extensible interface and means that "ctdb lvs
status" is also available.
Unit tests are streamlined so that there is a single test for each
CTDB state. Each test does "master", "list" and "status" sub-tests.

This is made slightly more difficult because the "env" command doesn't

used here is a bit fragile (assumes double-quotes, no nested quotes)
but this is test code and only developers are expected to use this
override.
