Make Job backoffLimit a configurable property

[kgrimes2]

💪 Motivation

I'd like to be able to set the backoffLimit property of KDP nodes to something other than the default of 6 when I deploy the operator.

📖 Additional Details

Nodes in KDP fail for several reasons, from running on EC2 spot instances that were evicted, to the host node running OOM. In most cases, just because Pods are failing, the entire pipeline shouldn't come to a halt.

⚖️ Acceptance Criteria

• When I deploy the operator, I can specify what the backoffLimit of Jobs should be
• Processing doesn't come to a standstill when any Node has its Pod die 6 times

⚙️ Engineering Details

• Update https://github.com/NASA-PDS/kdp/blob/main/operator/operator/manifests/node/job.yaml with a variable for backoffLimit
• Update https://github.com/NASA-PDS/kdp/blob/main/operator/operator/operator.py to pass that variable in from the input manifest (not exactly sure how this works, yet)

I think I can tackle this one, @ztaylor54 LMK if you see anything horribly wrong with this
