Improve vault management

I'm thinking in particular of:

• gcli vault generate --import, an option for generate command which imports the mnemonic instead of only displaying it
• gcli vault remove <address>, to allow removing account without going to the files

changed the description

Vault should also allow naming accounts and select account by name. For example:

gcli vault rename 5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY alice
gcli vault use alice

mentioned in merge request !40 (closed)

Just thought to update this one; those 3 were done in !41 (merged) :

• gcli vault remove <-a <ADDRESS>|-v <VAULT_NAME>>
• gcli vault rename 5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY
  • interactive prompt for the name
• gcli vault use <-a <ADDRESS>|-v <VAULT_NAME>>

Only one left:

• gcli vault generate --import, an option for generate command which imports the mnemonic instead of only displaying it

I used to decrypt my mnemonics with

rage --decrypt ~/.local/share/gcli/5Dq8xjvkmbz7q4g2LbZgyExD26VSCutfEc6n4W4AfQeVHZqz

Now that the mnemonic is in a db, I can still do:

sqlite3 ~/.local/share/gcli/gcli.sqlite "select encrypted_suri from vault_account where name = 'HugoGdev';" | rage --decrypt

But we could add a convenience command like gcli vault export -v HugoGdev.
