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 1/2] [pacemaker] Redesign node enumeration logic
It has been found that `pcs status` output is liable to change, which
ends up breaking our parsing of node lists when using it on newer
versions.
Instead, first try to parse through `crm_mon` output, which is what `pcs
status` uses under the hood, but as a stable and reliable xml format.
Failing that, for example if the `--primary` node is not functioning as
part of the cluster, source `/etc/corosync/corosync.conf` instead.

Subject: [PATCH 2/2] [clusters] Allow clusters to not add localhost to node
list
For most of our supported clusters, we end up needing to add the
local host executing `sos collect` to the node list (unless `--no-local`
is used) as that accounts for the primary node that may otherwise be
left off. However, this is not helpful for clusters that may reports
node names as something other than resolveable names. In those cases,
such as with pacemaker, adding the local hostname may result in
duplicate collections.
Add a toggle to cluster profiles via a new `strict_node_list` class attr
that, if True, will skip this addition. This toggle is default `False`
to preserve existing behavior, and is now enabled for `pacemaker`
specifically.

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.

From 2b2ad04884cfdda78c02a33a73603d249c0a4dd5 Mon Sep 17 00:00:00 2001
From: Jake Hunsaker <jhunsake@redhat.com>
Date: Tue, 19 Oct 2021 11:51:56 -0400
Subject: [PATCH 1/2] [Plugin] Allow writing command output directly to disk
This commit addresses a long standing ask in sos, regarding resource
consumption when sos is run with `--all-logs`.
For executions where `--all-logs` is used, or for specific commands
where `sizelimit` has been set to 0, `add_cmd_output()` and
`add_journal()` will now instruct `sos_get_command_output()` to write
output directly to a file rather than saving the output in memory.
When this occurs, the `output` key in the returned dict will be empty.
Note that this does extend to `collect_cmd_output()` or `exec_cmd()`.
Resolves: #1506
Signed-off-by: Jake Hunsaker <jhunsake@redhat.com>
