The kapacitor client used in the kapacitor endpoints is limited to
fetching whatever limit you provide it. If you provide no limit, it
defaults to a limit of 100. We use this default behavior currently.
Some users have more than 100 tasks, so we need a client that's capable
of continually fetching tasks from Kapacitor until there are none left,
and returning the full response to the frontend.
This introduces a PaginatingKapacitorClient which does exactly that.
Also, test coverage was added around the KapacitorRulesGet endpoint,
since it was previously untested.
