* Add option to throttle concurrent `helm repo update` calls

Have added a new flag `--concurrency N` to `helmfile sync charts` that can be used to set a
limit on the number of concurrent calls to helm. 

Implementation details:

Switched `SyncCharts` from using a WaitGroup to using a pool
of workers and a queue of jobs. To ensure that this is thread safe and
an attempt is made to sync each chart at the end.

Fixes #23

* Fix formatting and update CI to catch these errors

Have fixed the formatting so that `make pristine` now passes. Have also
added this to the Circle CI config to catch these errors in the future.
