The probe state is also used. It represents the time when the drive is being checked

We now automatically find all binaries to symlink into /usr/bin of containers.

Changes dispatcher back to using a switch statement for the EOS commands

Generating backtrace automatically when ctafrontend dies, collect it for artifacts and display it when the namespace gets deleted so that it appears on the Pipeline.

For the admin functions, it is very clunky to map <cmd,subcmd> pairs to

Previously when cta frontend coredumped, all the files appeared to have

I am now making sure cta client returned with no error to correctly
detect failures.
