httpapi connection support

[dvwh]

Currently, Mitogen supports several connection types like local, ssh, docker and more. However, it lacks support for httpapi.

Is it possible to reuse, adapt the existing connection plugins so httpapi can be used in Ansible plays with mitogen, or mitogen needs separate implementation of a connection plugin specifically for httpapi?

Workaround that seems to work:
