Remove 'peer' from name of channel client methods
Remove 'peer' from name of channel client methods

There is some inconsistent naming of RedChannelClient methods. Some
include the word 'peer' (which normally seems to refer to RedsStream).
Remove the 'peer' terminology from those functions that are basically
RedChannelClient methods.
