Security Key Pair creation is not allowed with "underscore" character from the Launch Instance menu on Horizon.

[David Hill]

Using Horizon to instantiate VM:
Instances -> Launch Instance -> Key Pair -> Create Key Pair
Trying to create Key Pair name with underscore character, getting "name contains bad characters" error - see attached screenshot.
If you are trying to create Security Key Pair prior to VM instantiation using Access & Security -> Create Key Pair, "underscore" character is accepted.
"Underscore" character shall be accepted in Security Key Pair name also in Instances -> Launch Instance -> Key Pair -> Create Key Pair menu.

    Allow keypairs to contain a underscore

    When manually creating keypairs, underscore are allowed but
    when creating keypairs while instanciating an instance, it's
    not allowed. This patch solves this.
