Implement contract verification during migration

[tarrencev]

When declaring new contracts, verify them with starkscan.

We should do this in a generic way to support future verification implementations.

Here is the Starkscan API info:
JSON def:
https://github.com/starkscan/starkscan-verifier/blob/acf3762c3ede91fe22a661e5b74c2e688289ffee/src/types.ts#L5
Endpoint:
https://github.com/starkscan/starkscan-verifier/blob/acf3762c3ede91fe22a661e5b74c2e688289ffee/src/api.ts#L78

Here is the Voyager API repo:

I can try this one

foundry has a very clean way of doing this. If you pass in your etherscan api key it will just automatically verify, so perhaps we follow a similar way

starkscan-verifier don't support cairo1 verifying yet, but I'll add all the code for the API call and we will enable once it's supported.

I'll have a look how it's done in foundry
