[Mochi] - Dynamic mocking

[hhalex]

Currently Mochi is ready to mock http routes statically in a very simple way. A key feature that wiremock supports is dynamic mocking, i.e. setup routes with an http rest api to execute a test suite for instance.

It could be nice to do the same, but may be in a different way, by keeping the "system/api" semantics, and deploy it on Mochi, with the same syntax we could use to describe mocks with the static api.
