Add DistroContext.install(). It takes a tar file containing secrets,
decrypts it, and installs all secrets needed on target and present in
that file. For every file that should be extracted, it logs if it
acutally did something or didn't.
It also features an only_missing argument, which is just a stub for
"allow to define somy extraction policy with respect to replacing all
/ some / not replace / whatever. Not thought through.

Cosmetics: The "packages" parameter to some DistroContext's methods
has a confusing name in same contexts, notably when mixed with a list
of Package instances, so rename it to "pkg_names".

The "secrets" class of commands currently only works on the host it's
invoked on. Use the current FileContext to allow using the existing
commands on a target host.
