Commit Message

test: gather kvstore output last

Log gathering is bounded by a timeout through a Context, so that the CI does
not get stuck if a single operation takes a long amount of time. However, if
one of the commands when gathering logs in the CI takes an inordinate amount
of time, all subsequent log-gathering commands will fail, because the Context's
deadline will have been reached. In a few CI runs, it has been observed that the
command to get the output from the kvstore has timed out, which is symptomatic
of broken connectivity to the kvstore from a given Cilium agent. Because this
command was ran as one of the first commands when gathering logs, if it timed
out, a lot of additional logs (e.g., bugtool, specific dumps, etc.) were not
performed because of the deadline being reached. So, this commit separates out
the kvstore log-gathering to be the file step of the log-gathering process in
the CI, so that if it times out, it will not affect gathering of other logs.
That way, if kvstore connectivity is messed up, we can have more actionable data
(bugtool, logs, etc.) to help debug the underlying issue. Make the timeout for
kvstore commands shorter than the entire timeout for log gathering because such
commands will hang infinitely if kvstore connectivity is in a bad state.
