feat: Add ability to add/delete relationship for all actors

[shahzadlone]

Relevant issue(s)

Resolves #3255

Description

• Can target all actors using "*" to add or delete acp relationships.
• All explicitly added relationships are unaffected upon revocation using "*" (they will keep access).

For Reviewers

• Commit by commit review should be easier.
• todo: Pushing the crashing gql tests fix once ci: Fix the gql mutation running in all tests #3267 is merged

Tasks

• I made sure the code is well commented, particularly hard-to-understand areas.
• I made sure the repository-held documentation is changed accordingly.
• I made sure the pull request title adheres to the conventional commit style (the subset used in the project can be found in tools/configs/chglog/config.yml).
• I made sure to discuss its limitations such as threats to validity, vulnerability to mistake and misuse, robustness to invalidation of assumptions, resource requirements, ...

How has this been tested?

• Integration tests

Specify the platform(s) on which this was tested:

LGTM. Just one minor todo before merge. And thanks for documenting in the acp readme.
