TODO: we want proper types for these
* AzureMonitor: Initial react Metrics editor components
* start dimension fields
* replace replaceTemplateVariable with datasource.replace, and rename onQueryChange to onChange
* actually just do template variable replacement in the datasource
* don't use azureMonitorIsConfigured
* Refactors, mainly around the metric metadata
- Convert all the metric metadata options for the Select before its set into state
- Stop using SelectableValue because it's basically any when all the properties are optional
- the onChange function passed to the fields now just accepts the direct value, rather than wrapped in a SelectableValue
