set_remote() <-> get_local()?

[Cory Johns]

get/set_remote deal with relation data sent over the wire.  get/set_local
never leave the unit in question and are simply there as a way to associate
information locally with a given remote unit.  Generally speaking,
get/set_local aren't actually what you want, and I wouldn't recommend using
them.  As for their implementation, get/set_local are basically just
calling charmhelpers.core.unitdata.kv().get/set with a key derived from the
conversation (e.g., the relation name and remote unit name), which stores
data in a local sqlite database.
