When we get a Second message in the candidate backing subsystem.

it should validate the candidate
- if it's an Invalid candidate, it should not be seconded. Instead, this subsystem should report to the collator protocol about invalidity.
afterwards, if we get another message to Second the candidate, If it's a valid candidate
- If backing is allowed, the subsystem should
  - Sign the statement
  - Import the statement into the statement table
  - and finally, issue a message to distribute the statement

candidate: It is a submitted parachain block to the relay chain validators. A parachain block stops being referred to as a candidate as soon it has been finalized
Statement could be either Valid or Seconded. (Seconded for this test)
- Seconded: The block is put forward by the para-validator to other para-validators (Implicit validity vote)
- Valid: statement that a validator has deemed a candidate valid
