DISPATCH-1739 Add -DUSE_BWRAP option, defaulting to OFF
Bubblewrap (https://github.com/containers/bubblewrap) is
an unprivileged sandbox. It allows running tests in parallel,
without any port clashes with already running servers.
> Use GitHub Actions w/ sharding and bubblewrap for some fast CI

> Key: DISPATCH-1739
> URL: https://issues.apache.org/jira/browse/DISPATCH-1739
> Project: Qpid Dispatch
> Issue Type: Improvement
> Components: Tests
> Affects Versions: 1.12.0
> Reporter: Jiri Daněk
> Assignee: Jiri Daněk
> Priority: Major
> Fix For: 1.13.0
>
>
> GitHub Actions is a task runner associated with a GitHub project. It is
> conceptually similar to Travis, except that it has some extra features, and
> the waits for computational resources are much shorter (currently).
> Sharding is a technique to speed up the execution of tests. Instead of
> running the tests on one machine one after another, copy the build directory
> over to multiple machines, say two, and have the first execute the
> odd-numbered and the second one the even-numbered tests. With luck (if
> copying the build directory is relatively fast, and the tests all take
> approximately the same time), this will cut the execution time in half.
> Bubblewrap (https://github.com/containers/bubblewrap) is a sandboxing tool
> available on Ubuntu and other systems. It is similar to systemd-nspawn except
> it does not require sudo or user namespace support in the kernel. It is
> similar to docker, except it does not use images, instead it selectively
> mounts directories from the host. Bubblewrap can create an isolated network
> namespace, which allows running multiple tests at the same time, each in its
> own bubblewrap sandbox, and they don't clash on ports. With bubblewrap,
> running {{ctest -j4}} is safe.
