* incapsulates multipleldap logic under one module
* abstracts users upsert and get logic
* changes some of the text error messages and import sort sequence
* heavily refactors the LDAP module – LDAP module now only deals with LDAP related behaviour
* integrates affected auth_proxy module and their tests
* refactoring of the auth_proxy logic
When allow_embedding is false (default) the Grafana backend
will set the http header `X-Frame-Options: deny` in all responses
to non-static content which will instruct browser to not allow
Grafana to be embedded in `<frame>`, `<iframe>`,
`<embed>` or `<object>`.
Closes#14189
Currently all API requests set Cache-control: no-cache to avoid browsers
caching sensitive data. This fixes so that all responses returned from
backend not are cached using http headers. The exception is the data proxy
where we don't add these http headers in case datasource backend needs
to control whether data can be cached or not.
Fixes#16845
* 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
Fixes#5356. Internet Explorer aggressively caches GET requests which
means that all API calls fetching data are cached. This fix adds a
Cache-Control header with the value no-cache to all GET requests to
the API.
