The Goal: we need to let the user use pg_stat_monitor source when adding remote PG server
Proposed solution: add an additional checkbox on https://pmmdemo.percona.com/graph/d/pmm-add-instance/pmm-add-instance? for PG Stat Monitor
an additonal line with checkbox, not selected by default : "Use PG Stat Monitor"
the user will have 3 options, so let's put them as for now as radiobutton:
Query metrics source:
- none (default)
- PG stat statement
- PG stat monitor
