Shard migration: Migrate cnf-testsuite org shards to main testsuite

[svteb]

Description

• After further discussion we have decided to migrate the shards in smaller batches that make sense (i.e. one shard = one commit).
• An overarching final commit will resolve all the dependency errors (require statements) and delete cnf-testsuite org shards from shard.yaml.
• Some apparent bug fixes will also be done in a shard's migration commit.

We have come to the conclusion that the shards should be moved to src/modules/<shard_name>/..., please comment if you know of a better placement.

The pull request is currently being blocked by #2221 and a future(?) cluster_tools pull request change, once these are done, we can proceed with moving them to main testsuite project.

Any major code refactors are subject to future pull requests, this is only migration.

Change log:

• Migrated tar (found out that due to duplicity conflicts between /lib and src/modules, the code breaks, thus we cannot merge until all shards are resolved). View this actions run for further info.
• Find module from find shard absorbed into tar (specifically tar_spec.cr, since the find shard only had a single function and it was only used in the spec tests of tar).

Issues:

Refs: #2219
