Pawan Dhananjay 56f9394141 Add cli option for voluntary exits (#1781)
## Issue Addressed

Resolve #1652 

## Proposed Changes

Adds a cli option for voluntary exits. The flow is similar to prysm's where after entering the password for the validator keystore (or load password from `secrets` if present) the user is given multiple warnings about the operation being irreversible, then redirected to the docs webpage(not added yet) which explains what a voluntary exit is and the consequences of exiting and then prompted to enter a phrase from the docs webpage as a final confirmation. 

Example usage
```
$ lighthouse --testnet zinken account validator exit --validator <validator-pubkey> --beacon-node http://localhost:5052

Running account manager for zinken testnet                                                                                                          
validator-dir path: "..."

Enter the keystore password:  for validator in ...

Password is correct

Publishing a voluntary exit for validator: ...              
WARNING: This is an irreversible operation                                                                                                                    
WARNING: Withdrawing staked eth will not be possible until Eth1/Eth2 merge Please visit [website] to make sure you understand the implications of a voluntary exit.            
                                                                                                                                             
Enter the phrase from the above URL to confirm the voluntary exit:
Exit my validator
Published voluntary exit for validator ...
```

## Additional info

Not sure if we should have batch exits (`--validator all`) option for exiting all the validators in the `validators` directory. I'm slightly leaning towards having only single exits but don't have a strong preference.

Lighthouse Account Manager

The account manager (AM) is a stand-alone binary which allows users to generate and manage the cryptographic keys necessary to interact with Ethereum Serenity.

Roles

The AM is responsible for the following tasks:

  • Generation of cryptographic key pairs
    • Must acquire sufficient entropy to ensure keys are generated securely (TBD)
  • Secure storage of private keys
    • Keys must be encrypted while at rest on the disk (TBD)
    • The format is compatible with the validator client
  • Produces messages and transactions necessary to initiate staking on Ethereum 1.x (TPD)

Implementation

The AM is not a service, and does not run continuously, nor does it interact with any running services. It is intended to be executed separately from other Lighthouse binaries and produce files which can be consumed by them.&

Usage

Simply run ./account_manager generate to generate a new random private key, which will be automatically saved to the correct directory.

If you prefer to use our "deterministic" keys for testing purposes, simply run ./accounts_manager generate_deterministic -i <index>, where index is the validator index for the key. This will reliably produce the same key each time and save it to the directory.
