add ignore collection syntax

[legrostdg]

It would be great to be able to ignore a specific collection (maybe based on a regex?), instead of having to specify all the collections one wants to synchronize.

I'd prefer not to use regexes, as the regex syntax is dependent on the programming language vdirsyncer is implemented in, it is probably very hard to replicate the exact syntax in another programming language. Globs may be an alternative.

[legrostdg]

OK. Globs would be great!

Does the 'ready' label means this is implemented?

[untitaker]

Nope, see https://vdirsyncer.pimutils.org/en/stable/contributing.html#the-issue-tracker -- this issue is ready to work on (no planning required/planning done)
