Have you discussed the design on the [forum](https://forum.snapcraft.io)? - [x] Have you successfully run `./runtests.sh static`? - [x] Have you successfully run `./runtests.sh unit`? ----- There is the desire for scriptlets to be able to communicate with Snapcraft, e.g. to request that it use a specific name, or version, or do a specific action, such as fetch stage packages, or run a lifecycle step. This PR resolves #1675 by adding the basic framework for this communication, adding a new CLI utility called `snapcraftctl` that is used to communicate with the parent Snapcraft process. It proves this out by adding a new subcommand to this utility called `build` which, if called, will run the plugin's build step. It also adds the `overide-build` scriptlet, which can use `snapcraftctl build` like so: # ... override-build: | snapcraftctl build # ... Note that, as a side-effect of this work, LP: [#1751749](https://bugs.launchpad.net/snapcraft/+bug/1751749) is fixed as well.
