improve(HubPoolClient): Permit selectively overriding search config (#…

…583)

This follows the pattern established in the SpokePoolClient, where
EnabledDepositRoute overriddes searchConfig.fromBlock on the first
update.

This will be used in the relayer to reduce the lookback for events
related to root bundles, since there's no need to query those all the 
way back to HubPool genesis.
