Bug: Failed to start Taiko client

Taiko-client failed to start, the error message is belowing.

CRIT [05-06|20:10:17.557] Failed to start Taiko client             error="abi: improperly encoded uint64 value"

After I searched for a while, I found that this error is caused by autogenerated code, which interacts with l1 contract.

By the way, taiko-client create client using backoff reconnection strategy, this definitely make the program more robust.

However, the implement lacks necessary logging when encountered network failed or execution server side err. The direct consequence of this, when configuration like endpoints are wrong or network error, the program will get stuck without any output, especially when users start the program, there is no error feedback.

Specifically, I suggested add a warning log when ethclient.DialContext(ctx, url) failed.
