Express Relay: directly submit Bids (#1747)

* SDKs now directly submitting to bid endpoint

* bump versions

* address comments

* remove development configs

* fix lint

* Add mode + better error handling

* Check chain ids before running simple searcher

* Update constants and adjust a bit for mode
