feat: added ignore pattern matching for filesystem plugin

[SHA65536]

I added the --ignore flag to let the user add patterns for files to be ignored. A user may supply multiple patterns using this form: 2ms filesystem --path path --ignore "*foo" --ignore "bar*"

I did not add tests as I am unsure how you guys want to test the plugins, worth discussing how a plugin test should be written.

Awaiting your feedback, cheers.

Close #93

Looks good to me! (see my comment)

Thanks @SHA65536!

@jossef Please review. The question is if you accept this approach of --ignore "*foo" --ignore "bar*" or did you expected to load a file with patterns (like .gitignore)?

[SHA65536]

We can support both, with an option like --ignorefile ignorelist.txt.
What are your thoughts?
