Add auxiliary search filter to the filtering log

[Alex-302]

Issue Details

The OS, various apps and websites continuously make a large number of requests, and heavily clog the filtering log, especially when protection is restarted (of added/modiffied the filtering rules, or changing filtering settings). When analyzing website requests, most of the lines are not related to the website (meaning the time interval from the start of the website loading to the performing of certain actions on the website).

Proposed solution

Add a domain and regular expression filters to hide addresses that clutter the filtering log and usually make no sense when working with filters (like OCSP servers, captchas, email clients, other sites with syncs including personal tabs, service domains, checks for updates of apps etc). It should be possible to disable this feature without clearing its filters.

How it looks in Fiddler:

Screenshot

Here are three useful features:

• hiding by hostnames (* is supported)
• show only a specific app's traffic (in AdGuard this is an undocumented feature)
• hiding by URL, URL part or by regexp

Can be opened as modal window (expandable, not extra small fixed sized even on lagre screens like in current v7 or in VPN)

@AdguardTeam/filters-maintainers Perhaps you also have suggestions on this issue.

Addition

Since the responsiveness of the Filtering Log interface depends on the number of lines, lines that matched by the auxiliary filter can be dropped.
