Add ability to deploy contracts to TestNet/MainNet from backend

[MetaB0y]

Recently we moved smart contracts to a separate repo and started to publish packages to GitHub npm registry.

Now it would be great to make it possible to deploy contracts from the back end.

Why do we need it now?

1. It would be more convenient to deploy from a web interface, you can do it from any device and don't need to care about the environment.
2. It should automatically add deployed contract to the list (see Add contracts storage list #1 ), therefore making it one step only.

Why would we need it later?
Because we will need to provide an interface to create a farm/vault for our end users. We probably cannot do it from the frontend (not sure yet, need to think more) because of wallets/authentication requirements.

Additional consideration:
Possibly it will need a mechanism to automatically create wallets and fund them from the Algorand faucet because of 10 apps per wallet limitation. Hopefully, this limitation will be lifted/worked around soon so maybe we will not need to think about it.

This is a lot of work and maybe will not be absolutely necessary but it is something to keep in mind and discuss now.

I see no particular problem in that, given that there is no more 10 apps per wallet limitation in Algorand. I already did frontend deployment in the vesting app, users can do that as well, we only need the backend to double-check the transaction before adding the contract metadata to the database (so that users cannot add random data to the backend).
