[Meta] Move rest of the Observability agent integrations to GA

[akshay-saraswat]

We have already moved 20+ agent-based Observability integrations from experimental or beta to GA. We should keep the momentum going towards the Beats → Agent migration and eventual GA so that we could reduce adoption friction for fleet and agent. Below is the list of packages that should be migrated as a second batch. This list is prioritized according to beats modules' usage telemetry as well as the number of ERs received. Should there be any hinders that prevent a package from moving to GA please highlight them here.

vSphere

• Make Vsphere GA #3508
• Fix [vSphere] Special Character in Password for vSphere SDK causes YAML parse error #3429
• Remove beta flag

IIS

• Fix IIS access Integration failed with unexpected pipeline error #2347
• Make IIS GA #3523
• Remove beta flag

CockroachDB

• Move cockroachdb module to GA #480
• Make CockroachDB GA #3550
• Remove beta flag

Hi! We just realized that we haven't looked into this issue in a while. We're sorry! We're labeling this issue as Stale to make it hit our filters and make sure we get back to it as soon as possible. In the meantime, it'd be extremely helpful if you could take a look at it as well and confirm its relevance. A simple comment with a nice emoji will be enough :+1. Thank you for your contribution!
