Deployment pipeline

[peersky]

Whenever a new version is released we want to do following BEFORE npm package is build & released for every network stored in NETWORKS="[<network_1>, <network...>, <network_n>] env variable that has form of json array:

1. If there is no existing deployment for contract artefact stored in /deployments/<network> directory:

• Deploy upgradable contract (proxy, implementation) & verify it
• Transfer ownership to a DAO (DAO_ADDRESS env variable)

2. If there is existing deployment:

• Should deploy implementation contracts
• Should create DAO proposal to upgrade
