feat: suppress default tags from module

[kayman-mk]

Description

#413 describes the problem of interfering default_tags of the provider and the tags created by this module. Sometimes it is useful to skip the resource tagging by this module for certain tags.

This PR adds the ability to not add some/all of the default tags created by this module. Set suppressed_tags to a list of tags you want to suppress. It works for tags, runner_tags and agent_tags. role_tags are not modified as they are used in addition to tags.

Closes #413

Migrations required

No.

Verification

• Deploy this version over the running version of the module. Make sure that the tags do not change.
• Set suppressed_tags = ["Environment"]. Deploy the module over an already deployed module. Check the plan and make sure that the Environment tag is removed.
