performance: optimize simplest case whether the ignoreip is a single IP (not subnet/dns) - uses a set instead of list (holds single IPs and subnets/dns in different lists);
...
decrease log level for ignored duplicates (warning is too heavy here)

amend to RC-fix 9f1c6f1617 (gh-2660):
...
resolves bottleneck by initial scanning of a lot of messages (or evildoers generating many messages) causes repeated ban, that will be ignored but could cause entering of "long" sleep in actions thread previously;
speedup recognition banning queue has entries to begin check-ban process in actions thread

failmanager, ticket: avoid reset of retry count by pause between attempts near to findTime - adjust time of ticket will now change current attempts considering findTime as an estimation from rate by previous known interval (if it exceeds the findTime);
...
this should avoid some false positives as well as provide more safe handling around `maxretry/findtime` relation especially on busy circumstances.

performance optimization of `datepattern` (better search algorithm);
...
datetemplate: improved anchor detection for capturing groups `(^...)`; introduced new prefix `{UNB}` for `datepattern` to disable word boundaries in regex;
datedetector: speedup special case if only one template is defined (every match wins - no collision, no sorting, no other best match possible)

filter processing:
...
- avoid duplicates in "matches" (previously always added matches of pending failures to every next real failure, or nofail-helper recognized IP, now first failure only);
- several optimizations of merge mechanism (multi-line parsing);
fail2ban-regex: better output handling, extended with tag substitution (ex.: `-o 'fail <ip>, user <F-USER>: <msg>'`); consider a string containing new-line as multi-line log-excerpt (not as a single log-line)
filter.d/sshd.conf: introduced parameter `publickey` (allowing change behavior of "Failed publickey" failures):
- `nofail` (default) - consider failed publickey (legitimate users) as no failure (helper to get IP and user-name only)
- `invalid` - consider failed publickey for invalid users only;
- `any` - consider failed publickey for valid users too;
- `ignore` - ignore "Failed publickey ..." failures (don't consider failed publickey at all)
tests/samplestestcase.py: SampleRegexsFactory gets new failJSON option `constraint` to allow ignore of some tests depending on filter name, options and test parameters

1492ab2247
improve processing of pending failures (lines without ID/IP) - fail2ban-regex would show those in matched lines now (as well as increase count of matched RE);
...
avoid overwrite of data with empty tags by ticket constructed from multi-line failures;
amend to d1b7e2b5fb2b389d04845369d7d29db65425dcf2: better output (as well as ignoring of pending lines) using `--out msg`;
filter.d/sshd.conf: don't forget mlf-cache on "disconnecting: too many authentication failures" - message does not have IP (must be followed by "closed [preauth]" to obtain host-IP).
