Glue: Correlations minor APIs behavior improvements (#56078)
* add correlation config type, CorrelationConfig validator & default values

* make config required when creating correlations

* make targetUID optional, add validation for createCommand & configType

* fix tests

* update remaining tests

* fix lint error

* Update pkg/services/correlations/models.go

Co-authored-by: Piotr Jamróz <pm.jamroz@gmail.com>

* update docs
