feat: replication mode awarenes in components

[bmuddha]

Request

Currently the validator cannot execute some transactions (or perform some certain other actions) if those were signed/triggerred by other validator. For the replication mode which is being developed as part of the #935, it's necessary to allow for those cases if the validator is operating in replica only mode (i.e. it has a different keypair identity, and only ever replicates without takeover). For those cases we should allow for:

1. the magicprogram to execute transactions which require validator signature, but don't have one
2. the committor service to ignore all intents
3. the crank to ignore newly registered tasks
4. for the chainlink to never clone anything, and in general be inert.
