[utilities] Allow size limits for command output

Previously, any command output generated from plugins from
add_cmd_output and add_journal would be collected in full in memory. For
example, if a journal was 4GB in size, then 4GB would be read into
memory and subsequently written to the final sos archive. This lead to
not only potentially large archives, but in some cases failure to
collect data or produce an archive due to memory constraints on the
system.

This patch adds the ability to use a sizelimit option in both
add_cmd_output and add_journal. This will limit the collected output
from commands or journals to the given limit, both what is read into
memory and what is written to the final archive. If not given,
sizelimit will default to --log-size. For journal collection, if no
sizelimit is given then the larger of either --log-size or 100mb is
used.
