Add faucet to send test tokens to accounts

[ebma]

It would be nice to have a faucet that we can use to top up accounts with testing tokens. Interlay has something for that implemented in Rust. We could do the same or implement it elsewhere. Hosting it online might be better so that the user does not have to run an extra service locally.

Will be estimated when implementation approach is defined / agreed.

Took a temporary approach to setup a account which product owns and can send tokens if and when needed by the vaults. Should we move this to a different epic?

Hey team! Please add your planning poker estimate with Zenhub @ashneverdawn @ebma @TorstenStueber

[ebma]

The implementation approach is still not really defined so it still wouldn't make much sense to estimate it.

@gonzamontiel we worked on a faucet in the past. Can you remember the status? Maybe we can reuse it here.

I think it could be reused, it was made with Netlify functions, so you needed to hit the URL with your account. We would need to change the RPC endpoint, the secret of the account meant for being the faucet, and maybe some other configuration options. But I would say it's ready to use.
