Run as non-root user and group
In the unlikely event that you are currently persisting data to disk then this
change may break file read/write access due to a change in the UID/GID that the
oauth2_proxy process runs as.
Run as non-root system user and group `oauth2proxy` with UID/GID `2000` to avoid clashing with typical local users.
An alternative to creating a separate user is to ~~chown binary and~~ run as `USER nobody`, which also works, can amend this PR if required.
Least access privileges.

* Update Changelog to reference https://github.com/pusher/oauth2_proxy/pull/68
* Fix Changelog message location
* Implemented flushing interval
When proxying streaming responses, it would not flush the response writer buffer until some seemingly random point (maybe the number of bytes?). This makes it flush every 1 second by default, but with a configurable interval.
* flushing CHANGELOG
* gofmt and goimports
