* Add tests for login view

* Fix OAuth auto login redirect loop

login_error cookie is only set when the OAuth login fails
for some reason. Therefore, the login view should return
immediately if a login_error cookie exists before trying
to login the user using OAuth again.

* Fix test

Use 'index-template' instead of 'index' for testing

* Add some comments

* Docs: Documents new features available with Loki data source in Explore

* Explore: Dispatches updateTimeRangeAction instead of passing absoluteRange when initializing
Also removes dependency on sinon from loki language provider test

* Loki: Refactors transformation of absolute time range to URL params into small utility function

* Makes use of rangeToParams() util function in loki language provider test
Also updates LanguageProvider.request() interface so that url should be type string, and adds optional params argument

Changes so a non-set seenAt property gets the createdAt value.

Fixes #17953

* LDAP:Docs: `active_sync_enabled` setting

Mention `active_sync_enabled` setting and enable it by default

* LDAP: move "disableExternalUser" method

Idea behind new design of the LDAP module is to minimise conflation
between other parts of the system, so it would decoupled as much as
possible from stuff like database, HTTP transport and etc.

Following "Do One Thing and Do It Well" Unix philosophy principal, other things
could be better fitted on the consumer side of things.

* feat: AzureMonitor implements legend key on backend

To be able to remove the duplicated query logic on the
frontend, the backend code needs to implement alias
patterns for legend keys as well as allowing the default
list of allowed time grains to be overridden. Some metrics
do not support all the time grains and the auto timegrain
calculation can be incorrect if the list is not overridden.

* feat: AzureMonitor - removes duplicate query logic on frontend

* AzureMonitor small refactoring

Extracted method and tidied up the auto time grain
code.

* azuremonitor: support for auto time grains for alerting

Converts allowed timegrains into ms and saves in dashboard json.
This makes queries for alerting with an auto time grain work in
the same way as the frontend.

* chore: typings -> implicitAny count down to 3413

* azuremonitor: add more typings

* Explore: Introduces storage keys for last used data source on per-orgId basis
Closes #17903

* Explore: Adds datasource plugin config option 'modesSupportingTextEdit'
This allows one to specify which modes support toggling query text edit on and off
Closes #17904

* Explore: Restricts query text edit toggle to metrics mode

In 42813448 the loadPluginCss util was migrated to @grafana/runtime package. This made SystemJS to fail loading the css files for a plugin. Root cause was that core and runtime used different SystemJS instances.

To solve the issue, I am exposing SystemJS from @grafana/runtime package to make sure we are always using the same instance. Also, the SystemJS dependency was moved to runtime.

Fixes: #17915 - Templating: __value's are displayed instead of __text's after variable is updated

Also replaces one-off segment detection functions in explore.ts with general purpose function
Closes #15462
