Support naming profiles after account alias or number

[acoppolawb]

Functionally a copy of Nike-Inc#294

Description

In many orgs (like mine) we use a single role in multiple accounts, and we name our aws profiles after the account name.

Resolves Nike-Inc#293

Motivation and Context

We have a lot of AWS accounts, and their names are long enough - using the roles makes it hard to use the cli with the resulting credentials.
