We don't need duplicate builds on pull requests and pushes.  This should
cut our actions essentially down to half of what they are now.

This is the first phase of refactoring the internal structure of the npm
commands to set us up for future changes.  This iteration changes the
function signature of `exec` for all the commands to be a async (no more
callbacks), and also groups all the commands into their own
subdirectory.

It also removes the Proxy `npm.commands` object, in favor of an
`npm.cmd` and `npm.exec` function that breaks up the two things that
proxy was doing. Namely, getting to the attributes of a given command
(`npm.cmd` now does this), and actually running the command `npm.exec`
does this.

Fix: #3962

When created from a hidden lockfile, shrinkwrap was always setting the
lockfileVersion to 3. The shrinkwrap command also needed to be updated
to log the correct message based on the lockfileVersion config instead
of the static lockfileVersion.

With these fixes, it was possible to log a better message whenever we
are changing the lockfileVersion, either from a config or any existing
lockfile.

Lastly, the tests for shrinkwrap were completely refactored to use the
real npm and test all conceivable scenarios, as well as removing usage
of `util.promisify` in favor of `fs.promises` now that we've dropped
support for Node 10.

Now that we make dependency upgrades as pull requests, this should make
them easier to review since GitHub will now render diffs for them by
default.

Windows no longer allows `file://`, but instead requires `file:///` for
local file urls.

Also after the command refactor things shifted and the tests didn't
catch that the help pages didn't work at all anymore, and that the
post-edit rebuild didn't work. This cleans up those two issues.
