The actual code to switch to master has been implemented only in the
standard and the fire-and-forget executor classes since it does not
make sense to have it in special executors used exclusively when in
client-side clustering mode.
This is a starting point to add a documentation of the whole set of APIs and
classes of Predis. The next step will be to actually improve and extend it.
