[draft] add empytdir mount to ee container in task pod

[kdelee]

SUMMARY

Mount a memory backed emptyDir to the ee container /tmp so receptor writes the job events its streaming back from job pods to memory instead of the container writable layer, which is copy-on-write.

ISSUE TYPE

• Bug, Docs Fix or other nominal change

ADDITIONAL INFORMATION

so far just works in local kind cluster
would like to test out and compare apples:apples and measure RAM usage, job event processing performance

I've built the operator container here: quay.io/kdelee/awx-operator:receptor-emptydir

Doesn't require any special awx image

Wonder if there is a desire to guard this in if statement with some var -- that said, I see the proliferation of vars as also a problem 😄

this should be done as a ee_extra_volume_mounts and task_extra_volumes and not used as a default...

memory are 💵
