optionally comma-delimited string to specify mulitple relay
groups. We can now have repeating values instead. To stay as
backward compatible as we can, we'll split any comma-delimited
strings and create one flattened list.
Thus, the following are all equivalent:
* `-r foo -r bar -r baz`
* `-r foo,bar,baz`
* `-r foo -r bar,baz
Additionally, if any relay groups are given, we'll verify they
actually exist; if all are real, we return their API
representations for use later. If any don't exist, we'll just stop
all processing right here.
