tx manager: staking on-chain interaction

[hopeyen]

Description

The most straight-forward way to make service available to protocol v1 involves deployments and allocations to an IPFS manifest that indicates their service. The possible units of deployments can be

1. a file containing the manifest of a set of files; allocation must be renewed when the set of files changes or when allocation lifetime expires
2. a file containing the server url; allocation must be renewed when url changes or when allocation lifetime expires

Regardless of the unit of deployment, they can be seen as an IPFS file. This PR consists of taking the IPFS file hash and

1. generate unique allocation signer and allocation id
2. allocation id proof for indexer ownership
3. ipfs hash converted to bytes32 representation
4. null array for metadata
5. populate allocate transaction, estimate gas, and send transaction

NOTE for UI:

1. require manual current epoch number
2. wallet subcommand takes allocate action
