* improve remote image rendering
- determine "domain" during Init() so we are not re-parsing settings
on every request
- if using http-mode via a rednererUrl, then use the AppUrl for the
page that the renderer loads. When in http-mode the renderer is likely
running on another server so trying to use the localhost or even the
specific IP:PORT grafana is listening on wont work.
- apply the request timeout via a context rather then directly on the http client.
- use a global http client so we can take advantage of connection re-use
- log and handle errors better.
* ensure imagesDir exists
* allow users to define callback_url for remote rendering
- allow users to define the url that a remote rendering service
should use for connecting back to the grafana instance.
By default the "root_url" is used.

* rendering: fixed issue with renderKey where userId and orgId was in mixed up, added test for RenderCallbackUrl reading logic
* rendering: headless chrome progress
* renderer: minor change
* grpc: version hell
* updated grpc libs
* wip: minor progess
* rendering: new image rendering plugin is starting to work
* feat: now phantomjs works as well and updated alerting to use new rendering service
* refactor: renamed renderer package and service to rendering to make renderer name less confusing (rendering is internal service that handles the renderer plugin now)
* rendering: now render key is passed and render auth is working in plugin mode
* removed unneeded lines from gitignore
* rendering: now plugin mode supports waiting for all panels to complete rendering
* fix: LastSeenAt fix for render calls, was not set which causes a lot of updates to Last Seen at during rendering, this should fix sqlite db locked issues in seen in previous releases
* change: changed render tz url parameter to use proper timezone name as chrome does not handle UTC offset TZ values
* fix: another update to tz param generation
* renderer: added http mode to renderer service, new ini setting [rendering] server_url
