[FEATURE] Request patterns for host name and IP addresses

This change adds RequestPatterns for host name and IP addresses.
Host names are configurable with a simple wildcard ('*') pattern, IP
addresses use ``CIDR`` style pattern with support for both ``IPv4`` and
``IPv6`` following ``RFC4632`` and ``RFC4291``.

Examples:

Only grant access to clients with IPs from 192.168.178.0 to
192.168.178.255::

TYPO3:
    Flow:
      security:
        firewall:
          rejectAll: TRUE
          filters:
            'ip':
              patternType:  'Ip'
              patternValue: '192.168.178.0/24'
              interceptor:  'AccessGrant'

Protect an area of your application file based authentication and IP
check (only trigger authentication and entry points for clients with an
IP of ``127.0.0.1``)::

TYPO3:
    Flow:

          providers:
            'LocalNetworkProvider':
              provider: 'FileBasedSimpleKeyProvider'
              providerOptions:
                keyName: 'AdminKey'
                authenticateRoles: ['Acme.SomePackage:Administrator']
              requestPatterns:
                controllerObjectName: 'Acme\SomePackage\Controller\Administration\.*'
                ip: '::7F00:1'
