[test][fix] Terminate all haproxy instances before testing
[test] Added more placeholder tests for all api methods
[api] Renamed the `connections` api to `ratelimit`
[api] Made the frontend optionally as settings can also be applied globally
[api] Merged the `setWeight` api with the `weight` api
[api] The arguments for the stats are now optional
[minor] Added missing `use strict` statement
[minor] Removed `module.exports` infavor of just `exports`
[codestyle] Don't use JSDoc for non function commenting, this makes API generation cleaner
[codestyle] Use `exports` instead of `parser` which is probably cleaner
[fix] Never throw errors @swaagie
[api] Implemented a draft implementation of the `verify` method.

The only thing i've noticed is that this is not gonna work when you want to edit
multiple configuration at the same time as they will be sharing the same `config`
global. The parser interface should probably be rewritten to something prototype
based.
[minor] Make it readable
