Dashboard: Adds support for a global minimum dashboard refresh interval (#19416)

Browse Source 
This feature would provide a way for administrators to limit the minimum 
dashboard refresh interval globally.
Filters out the refresh intervals available in the time picker that are lower 
than the set minimum refresh interval in the configuration .ini file
Adds the minimum refresh interval as available in the time picker.
If the user tries to enter a refresh interval that is lower than the minimum 
in the URL, defaults to the minimum interval.
When trying to update the JSON via the API, rejects the update if the 
dashboard's refresh interval is lower than the minimum.
When trying to update a dashboard via provisioning having a lower 
refresh interval than the minimum, defaults to the minimum interval 
and logs a warning. 

Fixes #3356

### min_refresh_interval
> Only available in Grafana v6.7+.
When set, this will restrict users to set the refresh interval of a dashboard lower than given interval. Per default this is not set/unrestricted.
The interval string is a possibly signed sequence of decimal numbers, followed by a unit suffix (ms, s, m, h, d), e.g. `30s` or `1m`.
