docker_available

Test if we can construct a docker client and confirm that we can
communicate with it. This is intended to help in debug connection
issues, and also for use in tests. For example, you might
implement a testthat skip test that skips if
<code>stevedore::docker_available()</code> returns <code>FALSE</code> to
conditionally use stevedore/docker within tests.

Work with containers over the Docker API.  Rather than
using system calls to interact with a docker client, using the
API directly means that we can receive richer information from
docker.  The interface in the package is automatically generated
using the 'OpenAPI' (a.k.a., 'swagger') specification, and all
return values are checked in order to make them type stable.
