Use SDK to poll and create smart order and handle result

Poll logic

Incorporate all the poll logic from the SDK

Why the logic is being moved to the SDK?

It is great to delegate to the SDK because:

• Watch Tower doesn't need to know what type of order is indexing.
  • See this PR for more details Poll conditional orders + Allow custom logic to delay checks to a given date, block, or forever cow-sdk#149
• The polling now will check on basic things like if the order is authorised (so we can remove that part of code from this project)
• The polling will also check on specifics of concrete orders: i.e TWAP could check if the order is expired so we don't try to index again

Auth Check in the SDK + Don't try again logic

The PR incorporate some handling of the poll result. Like when we don't need to try again to index an order.

Additionally, now by delegating to the SDK, we check out of the box if the order has been authenticated, and prints a nice message:

The watch tower will understand that this order doesn't need to be re-attempted in the future.

In order to test this, you can create an order and cancel it. Or you could index this block number:

BLOCK_NUMBER=29707125 
NETWORK=100

In case of success

This version will still successfully post the order to the API:

The only difference is that now, the responsibility of who is returning the discrete order details is in the SDK.

Network is not a String anymore

This PR changes the network from a String to a SupportedChainId. Since we use the SDK, it is nice we use its types.

Sorry for the noise on the chain.

One place where I didn't change it, is in the Registry that is persisted. I haven't update there yet to avoid making an incompatible chain in this PR. I prefer to avoid migrating the model for this.

To reproduce add this to your env

NETWORK=100
BLOCK_NUMBER=29707218

Utils refactor

The utils.ts was too big, i just broke it done into a few files.

Not included

• I have to do a typescript cast because the type we persist in the model don't match what we actually store. We should change the model, but for that we need to add migrations. This is completely out of scope of this PR: refactor: model #18
• Follow up PR will handle other results from the polling, like

Documenting an issue im having:

If you add this env:

NETWORK=100
BLOCK_NUMBER=29490646

And run with yarn start:actions

You will reproduce this:

This awaited promised were returning the 3 strings we need:

Now they return undefined

Its like the params is now an array of string and not an object with the named props (as typescript thinks):

An epic review. A few nits, and comments specifically dealing with merkle roots of orders.
