* 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
