Remote Labels Configuration

[aphralG]

Proposed changes

• Instead of sending a message on the bus to inform the plugins of changes to the agent config, added a Reconfigure function to the plugins. This allows the message bus before it processes a message to check if its a config update, if it is it validates and updates the new changes, then call reconfigure on each of the plugins and handles the data plane response.
• Add ability to modify labels when a change is made to the labels the otel collector if one exists is also updated and restarted with the new changes
