Add option to invoke the addressResolver on every call

[peterbroadhurst]

The address resolver is a very useful plug point for FireFly with EVM based chains that have sophisticated signing infrastructures.

We have a requirement for the interface to be called on every API call that has a key input on the Hyperledger FireFly API, regardless of whether the input string conforms to an 0x address already, and regardless of how many times it is called.

This PR introduces a single new config option alwaysResolve to do this.

I added a second commit on this PR, after doing quite a detailed review of every place we were calling the address
resolver. I found the terminology was still confusing (know we've had a few changes) and make a tweak.

I also made the following changes:

• Removed two places within the ethereum connector it was using the NormalizeSigningKey function, to just format an ethereum address. That is now fixed
• I removed the additional cache on address resolution that was in the Identity Manager, because this would have got int the way of the removal of the cache in the blockchain layer. Also, both Ethereum and Fabric already had caches for the expensive logic that wasn't just string formatting, so it seemed completely redundant.
• Fixed an intermittent coverage gap in Webhooks, fixing also the fact we were logging an error when there wasn't one, and removing a return of an error from doDelivery that was always nil

I ran the tests on this branch locally and have verified that there is no longer a gap in coverage, despite what codecov is reporting.

Looks good. Makes sense to me.
