packaging: add octez experimental debian package ( post-19.1 packages )

What

Add a debian package with a collection of binaries in the octez suite that do not fit in other packages. These are binaries that can be used for debugging or testing.

Since this package is just a container for octez binaries without services, or other installation script the reviwer should just check if the deb contains the binaries and those are correctly installed on the machine.

Why

How

Manually testing the MR

There is nothing much to test regarding this package except that the binaries are correctly installed and can be executed on the host. We do not add services, post or pre scripts.
