[Enhancement]: Explicit/implcit votes zombietest

[kamilsa]

Description

Create a zombietest that would:

1. Spin up a network with 8 validators (7 polkadot, 1 KAGOME), 2 parachains, 4 validators in each group
2. Check that KAGOME validator voted for every parachain block when it was assigned

Motivation

We need constantly ensure KAGOME node is participating in explicit/implicit voting

Additional context

• Test can run for 5 mins
• We need to
  • subscribe for new blocks (to any node)
  • for every block check:
    • Identify backing groups for each candidate
    • check that if KAGOME node belongs to some group (with configuration from description it should) it has issued either implicit or explicit vote

Are you planning to do it yourself in a pull request ?
