Log Message:
Updated security/fail2ban to 0.9.6.

Upstream changelog :
* Misleading add resp. enable of (already available) jail in database, that
  induced a subsequent error: last position of log file will be never retrieved \ 
(gh-795)
* Fixed a distribution related bug within testReadStockJailConfForceEnabled
  (e.g. test-cases faults on Fedora, see gh-1353)
* Fixed pythonic filters and test scripts (running via wrong python version,
  uses "fail2ban-python" now);
* Fixed test case "testSetupInstallRoot" for not default python \ 
version (also
  using direct call, out of virtualenv);
* Fixed ambiguous wrong recognized date pattern resp. its optional parts (see \ 
gh-1512);
* FIPS compliant, use sha1 instead of md5 if it not allowed (see gh-1540)
* Monit config: scripting is not supported in path (gh-1556)
* `filter.d/apache-modsecurity.conf`
    - Fixed for newer version (one space, gh-1626), optimized: non-greedy catch-all
      replaced for safer match, unneeded catch-all anchoring removed, non-capturing
* `filter.d/asterisk.conf`
    - Fixed to match different asterisk log prefix (source file: method:)
* `filter.d/dovecot.conf`
    - Fixed failregex ignores failures through some not relevant info (gh-1623)
* `filter.d/ignorecommands/apache-fakegooglebot`
    - Fixed error within apache-fakegooglebot, that will be called
      with wrong python version (gh-1506)
* `filter.d/assp.conf`
    - Extended failregex and test cases to handle ASSP V1 and V2 (gh-1494)
* `filter.d/postfix-sasl.conf`
    - Allow for having no trailing space after 'failed:' (gh-1497)
* `filter.d/vsftpd.conf`
    - Optional reason part in message after FAIL LOGIN (gh-1543)
* `filter.d/sendmail-reject.conf`
    - removed mandatory double space (if dns-host available, gh-1579)
* filter.d/sshd.conf
    - recognized "Failed publickey for" (gh-1477);
    - optimized failregex to match all of "Failed any-method for ... from \ 
<HOST>" (gh-1479)
    - eliminated possible complex injections (on user-name resp. auth-info, see \ 
gh-1479)
    - optional port part after host (see gh-1533, gh-1581)

* New Actions:
    - `action.d/npf.conf` for NPF, the latest packet filter for NetBSD
* New Filters:
    - `filter.d/mongodb-auth.conf` for MongoDB (document-oriented NoSQL database \ 
engine)
      (gh-1586, gh-1606 and gh-1607)

* DateTemplate regexp extended with the word-end boundary, additionally to
  word-start boundary
* Introduces new command "fail2ban-python", as automatically created \ 
symlink to
  python executable, where fail2ban currently installed (resp. its modules are \ 
located):
    - allows to use the same version, fail2ban currently running, e.g. in
      external scripts just via replace python with fail2ban-python:
      ```diff
      -#!/usr/bin/env python
      +#!/usr/bin/env fail2ban-python
      ```
    - always the same pickle protocol
    - the same (and also guaranteed available) fail2ban modules
    - simplified stand-alone install, resp. stand-alone installation possibility
      via setup (like gh-1487) is getting closer
* Several test cases rewritten using new methods assertIn, assertNotIn
* New forward compatibility method assertRaisesRegexp (normally python >= 2.7).
  Methods assertIn, assertNotIn, assertRaisesRegexp, assertLogged, assertNotLogged
  are test covered now
* Jail configuration extended with new syntax to pass options to the backend \ 
(see gh-1408),
  examples:
    - `backend = systemd[journalpath=/run/log/journal/machine-1]`
    - `backend = \ 
systemd[journalfiles="/run/log/journal/machine-1/system.journal, \ 
/run/log/journal/machine-1/user.journal"]`
    - `backend = systemd[journalflags=2]`
