cli: Differentiate between “local” accounts and on-chain accounts in terminology

[geigerzaehler]

At the moment the CLI uses the term “account” for two things.

First, for accounts on the block chain. A blockchain account is a balance and a nonce identified by a public key and the account can be controlled by the corresponding private key. The user interacts with these accounts through account show and account transfer

Second, we us “account” for key pairs stored locally on disk. These key pairs are identified by a name. The user interacts with them through account generate and account list.

Mixing the terminology leads to user confusion.

@cloudhead is suggesting to use the term “key pair” for accounts stored on disk. This would mean we replace the respective account commands with key-pair generate and key-pair list.

Sounds good to me. Considering #413, we would have the following under the key-pair group, which is rather sound:

> key-pair generate
> key-pair list
> key-pair import
> key-pair export
