Service Plans: Add floating, ala carte plan.

[arebacollins]

We have packages, and have one specific package where a client can choose how many Mbps they want and we put in, based on a flat , per Mbps pricing. Is it possible to define a service once, say "Dedicated Internet" with a base , per Mbps price, say "Ksh 6500 / mbps", which then when adding service plans we can add to a client, with an integer taking the volume of Mbps taken, so we then have a client who buys 7 mbps getting a service plan for Ksh 45,500 each month, and vice versa.

Interesting. I am looking to make a few pull requests.
