Implement account forget

[sushi30]

Description

This command, according to the docs, should remove an account from local memory:

forget      Remove/Forget an account

This is obviously useful form local testing scenarios but also in production for sweeping accounts.

Scenario

When using this command:

$  webb account forget

Output:

thread 'main' panicked at 'not yet implemented: forget account', src/commands/account.rs:186:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Expected

Delete the account by alias or by address.

Proposed Solution

I saw this is not yet implemented so I will take this and implement if no one minds.

Awesome! Can you describe more deeply the issue and link to the description you saw as unimplemented?

It would be great to ensure the CLI works against the master, develop, and erup-4 branches. These are the ones we are currently working on in parallel. master and develop are explanatory. erup-4 is targeting the Edgeware Runtime Upgrade Proposal #4 that will add this runtime functionality to the Edgeware blockchain.

Hi, added some more meaningful description. Let me know if you need any more information.

Awesome sounds good! I'd also recommend testing to make sure this CLI works against master and erup-4 branches of the anon node.
