Multiple accounts/instances support?

[msva]

Hi there! It would be nice, if terjira (I mean, it's in-the-box cli tool) would somehow support working with multiple jira instances (say, for freelancers, that can work on contract with multiple companies having separate jira instances).

I thinking of it like, maybe, supporting multiple "profiles" (in ~/.terjira/profile), and having an easy way way to switch between them (or even specify if as --arg).
