Adding a configurable Supervisor ID

[markobachvarovski]

Description

Adding the option to enter the Supervisor ID before first launch. This is particularly useful when pre-registering collectors

#45596

Fixes

Testing

Extended the persistence tests to also test the following scenarios:

1. When creating a persistent_state file, if instance_id is provided, use that as the instance_id
2. If instance_id is not provided or is provided but is invalid, fall back to creating one randomly (existing behaviour)

Manually tested and verified that changing isntance_id after first launch does NOT return the modified instance_id, meaning once it's persisted to file, config changes don't affect it (as expected)
