jw-pkg.py secrets [sub-command] [packages] is a set of utility
commands designed to manage configuration files containing secrets.
To keep secrets from leaking via version control or packages, a
_template_ should be packaged for every sensitive configuration file.
Then, during post-install, configuration files can be generated from
packaged templates via
jw-pkg.py secrets compile-templates <package> <package> ...
During post-uninstall
jw-pkg.py secrets rm-compilation-output <package> <package> ...
removes them.
Not specifying any packages will compile or remove all templates on
the system.
To identify which files to consider and generate or remove, the
compilation scans <package> for files ending in .jw-tmpl. For each
match, e.g.
/path/to/some.conf.jw-tmpl
it will read key-value pairs from
/path/to/some.conf.jw-secret
and generate
/path/to/some.conf
from it, replacing all keys by their respective values. The file
attributes of the generated file can be determined by the first line:
of some.conf.jw-tmpl or some.conf.jw-secret:
# conf: owner=mysql; group=mysql; mode=0640
There are other commands for managing all secrets on the system at
once, see jw-pkg.py secrets --help:
compile-templates Compile package template files
list-compilation-output
List package compilation output files
list-secrets List package secret files
list-templates List package template files
rm-compilation-output
Remove package compilation output files

DistroBase's option --id is now redundant to the new global option
--distro-id in the App class, so remove --id. The only added value
DistroBase then brings to the table is its .distro property, which
can be provided by App just fine at this point, given that App has
all it needs to construct a Distro object, so add .distro to App and
remove the entire DistroBase class.
For convenience, also make App.distro available as a newly added
cmds.Cmd.distro property. This also obviates the need for the
distro-related properties in the .distro.Cmd class, remove all that.

Add the --verbose global option, which is made available as the

Some functions still take a verbose parameter, but the type of these
parameters is converted from bool to bool|None. The idea is that, if

The code below lib.distro, as left behind by the previous commit, is
geared towards being directly used as a command-line API. This commit
introduces the abstract base class Distro, a proxy for
distribution-specific interactions. The proxy abstracts distro
specifics into an API with proper method prototypes, not
argparse.Namespace contents, and can thus be more easily driven by
arbitrary code.
The Distro class is initialized with a member variable of type
ExecContext, another new class introduced by this commit. It is
designed to abstract the communication channel to the distribution
instance. Currently only one specialization exists, Local, which
interacts with the distribution and root file system it is running
in, but is planned to be subclassed to support interaction via SSH,
serial, chroot, or chains thereof.

Functions abstracting the distribution are not only needed in the
context of the distro subcommand, but also by other code, so make the
bulk of the code abstracting the distribution available in some place
more universally useful than below cmds.distro.
This commit leaves the source files mostly unchanged. They are only
patched to fix import paths, so that functionality is preserved.
Refactoring the code from command-line API to library API will be
done by the next commit.
