Managed wallet API

[baktun14]

Why

We want to make it possible for users to integrate with Akash programmatically using our managed wallets api. Currently it's only possible to manage deployments using the console and users are requesting to do the same using our API.

Solution

The first iteration of this system will consist of implementing API keys for users to give access to the /v1/tx endpoint to sign transactions to manage deployments (create/update deployment, create lease)
