tools and systemtap containers are available in Fedora

[Tomas Tomecek]

Hello,

we managed to move tools container from Fedora Dockerfiles github repo to
Fedora infra [1]. As a side effects, we put systemtap in a dedicated
container.

We would very much appreciate your feedback here: so if you have some time
to take a look at these containers and try them out, it would mean a lot to
us.

The way to access the images:

docker pull candidate-registry.fedoraproject.org/f26/systemtap

Both images have help files, so please read them prior using the containers:
