Change microversion header

[Jamie Hannaford]

The API-WG has recently published a guideline for microversions [1]. Magnum already meets this standard for the most part, except for the fact that it uses this header:

X-OpenStack-Magnum-API-Version: 1.20

which is incorrect. The new recommendation is to have this:

X-OpenStack-API-Version: magnum 1.20

We will need to change the parsing logic to accommodate this.
