supporting standard api version format rsther than numbers

[AmirSasson]

rather integers that represent the api version, most api versions are represented as "yyyy-mm-dd-preview" or yyyy-mm-dd.
these formats can be parsed to apiVersion which implements icomparable.
in addition why is there a limitation of only a single api version which is supported/active and all other are deprecated?

In order to work it tags controllers/actions with every version between introduced and removed. There is no way to do this with dates.
