 - **all**: rename plugin IDs from `pcp-*-*` to `performancecopilot-*-*`

 ### Breaking Changes
 - the internal plugin IDs of the data source and panel plugins were renamed from `pcp-X-Y` to `performancecopilot-X-Y`, for example `pcp-redis-datasource` was renamed to `performancecopilot-redis-datasource` in order to conform to the Grafana plugin id naming conventions
