[aleksostapenko]

According to #844, functional test for checking requests whitelisting is needed. Test should verify following scenario:

1. Set some mark for particular type of incoming network packets (via nftables interface)
2. Configure whitelisting with corresponding mark in Tempesta via directive whilelist_mark <mark>
3. Enable Frang and Sticky cookie (with enforce option) modules in Tempesta configuration
4. Check that requests of specified in p.1 type are not filtered out via Frang and not answered with 302 response
