Move test IRC statusbot config into test specific vars file

The statusbot role defined a number of defaults that really only made
sense for testing. The actual values are expected to be overridden in
private vars. To better convey this and to avoid using defaults that
aren't expected to work quite right refactor the variable definitions
into the ansible vars file used by zuul jobs in testing.
