Azure Functions bindings

[ulrikstrid]

Some stuff works and some don't. I seem to need some help here, I have used the Lamda implementation as a base but I seem to be doing something wrong when I pass stuff to runHttpQuery.

All tests pass, I have to find another type definition for Azure Functions or just write my own.

Changed to @christopheranderson's lib for the types. I'm not sure what you want me to write in the CHANGELOG and if it is a new version or how this works.

TODO:

• Update CHANGELOG.md with your change (include reference to issue & this PR)
• Make sure all of the significant new logic is covered by tests
• Rebase your changes on master so that they can be merged easily
• Make sure all tests and linter rules pass

what is use case of azure fn for graqphql ?

[ulrikstrid]

Same as for aws I guess. Which for me would probably be as a proxy for othet APIs. Now with dureable functions on Azure it makes even more sense as we don't have to incur the cost of compiling the schema every time.
