HipChat allows users to run their own private servers and to be able to
support those we must connect to the correct URL when using one of these
custom servers.
HipChat refers to their own product camel cased so we should do the
same. HipChat no longer recommends people use the deprecated v1 API so
switch to using the v2 API by default. hipchat-rb does not yet default
to v2 in any version so it must be specified.
per changes with slack, they’re now using “static” web hook urls that describe the team & service with IDs that don’t change if the team or service name change. their recommendation is to use the raw webhook_url instead of building it out of components to allow more flexibility
this should also prevent issues cropping up with mistakes in how the urls are parsed
