When running a support bundle, we want to know how long each operation
(collect, redact, analyze) takes. This commit adds a new trace exporter
that records the start and end times of each operation, and then prints
a summary of the execution. The summary is also stored in the support
bundle.
Related to #923
introduces a new option to limit the size of a pod log when added to the bundle. This will make sure the support bundle will not grow to an unacceptable size and thus might contain information that is too old.
The maximum size of a pod log in a bundle is set by default to 5MB, and can be changed if we decide upon the need.
BREAKING CHANGE: any logs that are collected by the logs collector are now limited by default to 5MB unless a different size limit is specified. Folks expecting log files larger than that to be collected without truncation will need to adjust their support bundle specs.
Fixes: #878
* feat(collectors): Store all pod logs in cluster-resources directory
All pod logs collected by the logs collector will now be stored in
/cluster-resources/pods/logs/[namespace]/[pod]/[container].log. This
will provide consistency and allow sbctl to find the logs when we run
`kubectl logs <pod>`. To allow backwards compatibility, symlinks of the
log files will be created in the current expected locations.
Closes: #744
