[stgt] tgt-admin behavior with multiple targets and same account name

[Chandra Seetharaman]

Looks like it will lead to confusion if we allow the account to be
defined at the target level.

May be we should define the account (account name and password) at the
global level and have just the "association" at the target level, what
do you think ?
