Notify the response ops when there is change on connector config (ela…

…stic#175981)

Resolves: elastic#175018

This Pr adds an integration test to check the changes on connectorTypes
config, secrets and params schemas.
I used `validate.schema` field as all the connector types have it.

ConnectorTypes has config, secrets and params schemas on
`validate.schema` whereas SubActionConnectorTypes has only config and
secrets.

They have multiple params schema as well but only registered and used
during action execution.
e.g.
https://github.com/ersin-erdal/kibana/blob/main/x-pack/plugins/stack_connectors/server/connector_types/bedrock/bedrock.ts#L57

And here is the explanation why they are not listed in a definition:

https://github.com/ersin-erdal/kibana/blob/main/x-pack/plugins/actions/server/sub_action_framework/validators.ts#L38

We need to do some refactoring to list those schemas on the connector
types.
