[Bug 1877171] [NEW] Purge, instead of just remove, the old kernel

[Amr Ibrahim]

Public bug reported:

update-manager automatically removes the old kernel while installing
updates, which is a great thing.

However, I assume it only performs an "apt remove", instead of "apt
purge" on the old kernel because its configuration file still exists
after its removal. (One can know that by setting a custom filter in the
Synaptic package manager).

I believe that update-manager should purge the old kernel instead of
just removing it to get rid of its configuration file because it would
be useless without the kernel.
