Publish micro_http to crates.io

@jiangliu and @sameo were asking/suggesting to publish our micro_http implementation to crates.io.
I am opening this issue to discuss if this is something that we want to do. I don't believe that rust-vmm is the appropriate organization for this crate as the micro_http is not really related to VMMs, so we will need to be hosting it in some other place.

No files, tests, or entry points are named. Start by reading the repository and the eight-comment discussion, then determine whether micro_http should be published and where it should be hosted; done means the hosting and publication plan is agreed and documented.
