V2 Handle a case where priorityFee > maxFee in the task loop

[thomaspanf]

Automatic transactions in the task loop fail when the user-inputted priorityFee is greater than the oracle based maxFee. This PR addresses this case by setting priorityFee to min(priorityFee, 25% of the oracle based maxFee) when priorityFee > maxFee for transactions in the node task loop.

This PR slightly differs from #655 because it includes:

• A new type: GasSettings to consolidate related gas fields and a pointer reciever ApplyTo to apply the gas settings to opts *bind.TransactOpts
• A unit test for ApplyTo
