Subject: [PATCH] [report] Calculate sizes of dirs, symlinks and manifest in
estimate mode
Enhance --estimate-mode to calculate sizes of also:
- symlinks
- directories themselves
- manifest.json file
Use os.lstat() method instead of os.stat() to properly calculate the
sizes (and not destinations of symlinks, e.g.).
Print five biggest plugins instead of three as sos logs and reports do
stand as one "plugin" in the list, often.

As --estimate-only calculates disk usage based on `stat` data that
differs from outputs of other commands like `du`, enhance the warning

Also add a rule-of-thumb recommendation of real disk space requirements.

Subject: [PATCH] [utilities] Don't try to chroot to /
With the recent fix for sysroot being `None` to always being (correctly)
`/`, we should guard against situations where `sos_get_command_output()`
would now try to chroot to `/` before running any command. Incidentally,
this would also cause our unittests to fail if they were run by a
non-root user.

Subject: [PATCH] [Systemd, Policy] Correct InitSystem chrooting when chroot is
needed
This commit resolves a situation in which `sos` is being run in a
container but the `SystemdInit` InitSystem would not properly load
information from the host, thus causing the `Plugin.is_service*()`
methods to erroneously fail or return `False`.
Fix this scenario by pulling the `_container_init()` and related logic
to check for a containerized host sysroot out of the Red Hat specific
policy and into the base `LinuxPolicy` class so that the init system can
be initialized with the correct sysroot, which is now used to chroot the
calls to the relevant `systemctl` commands.
For now, this does impose the use of looking for the `container` env var
(automatically set by docker, podman, and crio regardless of
distribution) and the use of the `HOST` env var to read where the host's
`/` filesystem is mounted within the container. If desired in the
future, this can be changed to allow policy-specific overrides. For now
however, this extends host collection via an sos container for all
distributions currently shipping sos.
Note that this issue only affected the `InitSystem` abstraction for
loading information about local services, and did not affect init system
related commands called by plugins as part of those collections.

Subject: [PATCH] [Plugin,utilities] Add sysroot wrapper for os.path.join
Adds a wrapper for `os.path.join()` which accounts for non-/ sysroots,
like we have done previously for other `os.path` methods. Further
updates `Plugin()` to use this wrapper where appropriate.

Subject: [PATCH] [global] Align sysroot determination and usage across sos
The determination of sysroot - being automatic, user-specified, or
controlled via environment variables in a container - has gotten muddied
over time. This has resulted in different parts of the project;
`Policy`, `Plugin`, `SoSComponent`, etc... to not always be in sync when
sysroot is not `/`, thus causing varying and unexpected/unintended
behavior.
Fix this by only determining sysroot within `Policy()` initialization,
and then using that determination across all aspects of the project that
use or reference sysroot.
This results in several changes:
- `PackageManager()` will now (again) correctly reference host package
lists when sos is run in a container.
- `ContainerRuntime()` is now able to activate when sos is running in a
container.
- Plugins will now properly use sysroot for _all_ plugin enablement
triggers.
- Plugins, Policy, and SoSComponents now all reference the
`self.sysroot` variable, rather than changing between `sysroot`.
`_host_sysroot`, and `commons['sysroot']`. `_host_sysroot` has been
removed from `Policy`.

Subject: [PATCH] [policies] Set fallback to None sysroot
9596473 commit added a regression allowing to set sysroot to None
when running sos report on a regular system (outside a container). In
such a case, we need to fallback to '/' sysroot.
Resolves: #2846
