Split gather_network_logs into basics and extras

[flavio-fernandes]

With OVNK-Interconnect support in 4.14, ovnkube-nodes logs grew large. This commit adds the ability to either collect or skip the additional logs.

Script changes:

• collection-scripts/gather_network_logs_basics now used as the "regular" gather script.
• Renamed collection-scripts/gather_network_logs to collection-scripts/gather_network_logs_basics.
• Improved gather_network_logs to invoke gather and collect additional logs beyond basics.

@npinaeva I uploaded the MG here: https://drive.google.com/drive/folders/1eXyp_wJ5-VoiDKaZv8xg4cMgFOHM_oH4?usp=drive_link

In the process, I hit an error I did not expect when using the mg images: no rsync! :( so I'm super glad you asked mt to try it because I was assuming it would work just as well outside the mg image. The drive with link above includes the commands I tried:

❯ oc adm must-gather --image=quay.io/ffernand/mg:${TAG} -- gather_network_logs 2>&1 | tee ~/collect.txt
❯ tar tzvf ./must-gather.loc*/quay-io-ffernan*/network_logs/ovnk_extras_store.tar.gz
