feat(inputs.diskio): Allow selecting devices by ID

[srebhan]

• Updated associated README.md.
• Wrote appropriate unit tests.
• Pull request title or commits are in conventional commit format

resolves #11685

This PR will try to resolve all given devices on Linux, i.e. follow the (potential) symlinks of each device to their native "name"/device file which is helpful when specifying disk-ids or uuids. Furthermore, the PR adds the WWID of disks as tag.

Note: All of the above will only work on Linux and only if there are no wildcards used!

I like it! What do we need to add the docs?

[Hipska]

Can this be tested somehow?

[powersj]

@srebhan I think all that is waiting is doc updates and now conflicts resolved

[srebhan]

@powersj is this what you had in mind?
