* Reapply MetricNamespace support
* Fixing tests
* refactor: move metricnamespace param to backend
* refactor: remove unused function
* azuremonitor: migration for new metric namespace field
* azuremonitor: add template query for metric namespace with a sub
* docs: template queries for azure monitor
Adds new lines for the metricnamespace template function and fixes
some messed up lines
* 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
* fix: azuremonitor adds multi-sub support to alerting
* fix: AzureMonitor missing parameter in metadata func
getMetricMetadata function when called in the query ctrl
was missing a parameter for Subscription Id.
Also, made some tweaks to what happens when a chained
dropdown is changed to not reset all the fields that
are dependent on it.
