Reduce perceived complexity of capability computation

Closes #216879

See merge request gitlab-org/gitlab!33394

This enables rspec foss-impact job to run
in community and security forks

This job runs in gitlab MR pipelines when
the pipeline is a pipeline for merged result.

It runs as if foss, without ee/ directory.
It detects ruby foss files changed and runs matching
rspec test files to detect any EE dependency
that might exist in FOSS.

New created projects inherit instance integration

See merge request gitlab-org/gitlab!32775

Creating a new project should inherit the integration settings from the
instance-level integration before trying from the template.

There were a couple new issues that were caused by Gitaly absorbing
gitlab-shell functionality:

1. The Gitaly `config.toml` now needs the URL of the GitLab host
(https://gitlab.com/gitlab-org/gitaly/-/merge_requests/2168).

2. `.gitlab_shell_secret` is now read by Gitaly at startup
(https://gitlab.com/gitlab-org/gitaly/-/merge_requests/2214).

3. Praefect SQL failover is now enabled by default
(https://gitlab.com/gitlab-org/gitaly/-/merge_requests/2218). We can
disable this for now since we don't need this for the GitLab tests.
