Adds support for collecting metrics from backend plugins and 
exposing them thru Grafana's Prometheus metrics endpoint. 
Enables to check health of backend plugin by using the route
`/api/plugins/<plugin id>/health`.
Uses sdk v0.6.0.

Closes #20984

By rotating the auth tokens at the end of the request we ensure
that there is minimum delay between a new token being generated
and the client receiving it.
Adds auth token slow load test which uses random latency for all 
tsdb queries..
Cleans up datasource proxy response handling.
DefaultHandler in middleware tests should write a response, the 
responseWriter BeforeFuncs wont get executed unless a response
is written.

will not be set, but if none the attribute will be set and is a
breaking change compared to before where none did not render the
attribute. This was due to a known issue in Safari.

OpsGenie's model works heavily off of the priority of an alert, 
e.g. routing and escalation. Currently this plugin only supports 
the default "P3".
Setting a tag og_priority to the correct P-value, e.g. P1, P2, P3, 
P4 or P5, will call the OpsGenie API with the correct priority value 
set.

Add fallbackText to Google Chat notifications. 
Definition of fallbackText: A plain-text description of the message's 
cards, used when the actual cards cannot be displayed, 
e.g. mobile notifications.

Fixes #21463

Alerting: Adds support for sending a single email to all recipients in notification channel (#21091)

When an alert is sent by e-mail, the process sends an e-mail to 
each recipient separately. This PR is a single delivery to all recipients.
For companies that use e-mail extensively, this is necessary in order 
not to overload the sending queue.
