Description of problem:


When creating an activation key using the activation key page (https://access.redhat.com/management/activation_keys), I would like the ability to not have to set an SLA. Today, the current UI forces me to select an SLA (Premium|Standard|Self-Support).

This can have unintended effects as the activation key that is defined on the key sets the SLA on the consumer. And if the consumer is a virtual guest you will have unpredictable behavior when it is migrated to a host with a different SLA. 

Also, Candlepin matches SLA exactly, so setting an SLA of Standard means 'exactly standard', not 'standard or better', which is confusing to the end user.
