NO-JIRA: Running gather scripts in background

[OdedViner]

To save time when running the OCP MG, the collection scripts can be executed in parallel.

Process: 1.Collect script 2.Waiting on subprocesses to finish execution.

Tested on my cluster and we can save 20% run time:

oviner:my_image$ time oc adm must-gather --image=quay.io/oviner/ocs-must-gather:ocp_mg2
real    7m49.209s
user    0m13.960s
sys     0m4.095s

oviner:regular_image$ time oc adm must-gather --image=quay.io/openshift/origin-must-gather:latest 
real    9m44.340s
user    0m14.055s
sys 0m4.115s

Hi @OdedViner. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
