Subject: [PATCH] [runtimes] Allow container IDs to be used with
`container_exists()`
As container runtimes can interchange container names and container IDs,
sos should also allow the use of container IDs when checking for the
presence of a given container.
In particular, this change unblocks the use of `Plugin.exec_cmd()` when
used in conjunction with `Plugin.get_container_by_name()` to pick a
container based on a provided regex that the container name may match.
Related: #2856

Subject: [PATCH] [sosnode] Handle downstream versioning for runtime option
check
First, adds parsing and formatting for an sos installation's release
version according to the loaded package manager for that node.
Adds a fallback version check for 4.2-13 for RHEL downstreams that
backport the `container-runtime` option into sos-4.2.
Carry this in upstream to account for use cases where a workstation used
to run `collect` from may be from a different stream than those used by
cluster nodes.

Subject: [PATCH] Improve sos collect for OCP: 1. wait for sos tmp project to
be deleted (just calling delete changes project state to Terminating, and
running a new sos collect is not possible before this project is fully
deleted) 2. use --retries flag to copy sos reports from the nodes more
reliably. The flag has been recently added to kubectl, and the most reliable
way to check if it's available or not is to check command error output for
"unknown flag" substring

Subject: [PATCH] [Plugin] Allow plugins to define default command environment
vars
Adds the ability for plugins to define a default set of environment vars
to pass to all commands executed by the plugin. This may be done either
via the new `set_default_cmd_environment()` or
`add_default_cmd_environment()` methods. The former will override any
previously set values, whereas the latter will add/update/modify any
existing values.

Subject: [PATCH] [presets] Adjust OCP preset options
Adjust the options used by the 'ocp' preset to better reflect the
current collection needs and approach.
This includes disabling the `cgroups` plugin due to the large amount of
mostly irrelevant data captured due to the high number of containers
present on OCP nodes, ensuring the `--container-runtime` option is set
to `crio` to align container-based collections, disabling HTML report
generation and increasing the base log size rather than blindly enabling
all-logs.

Subject: [PATCH] [ocp, openshift] Re-align API collection options and rename
option
Previously, in #2888, the `openshift` plugin was extended to allow API
collections by using a default-available kubeconfig file rather than
relying on user-provided tokens. This also included flipping the default
value of the `no-oc` plugin option to `True` (meaning do not collect API
output by default).
This worked for the plugin, but it introduced a gap in `sos collect`
whereby the cluster profile could no longer reliably enable API
collections when trying to leverage the new functionality of not
requiring a user token.
Fix this by updating the cluster profile to align with the new
default-off approach of API collections.
Along with this, add a toggle to the cluster profile directly to allow
users to toggle API collections on or off (default off) directly. This
is done via a new `with-api` cluster option (e.g. `-c ocp.with-api`).
Further, rename the `openshift` plugin option from `no-oc` to
`with-api`. This change not only makes the option use case far more
obvious, it will also align the use of the option to both `collect` and
`report` so that users need only be aware of a single option for either
method.
The cluster profile also has logic to detect which plugin option,
`no-oc` or `with-api` to use based on the (RHEL) sos version installed
on the nodes being inspected by the `ocp` cluster profile.
