Nats Nack missing k8s components.

[BenCoughlan15]

Hey there!

I've deployed nats-nack, but I can see it's missing the following important components.

RESOURCES:

not that it uses a whole pile, but it would be good to have a handle on this, with sensible defaults.

• limits.cpu
• limits.memory
• requests.cpu
• requests.memory

PROBES:

pretty important for health checks, etc.

• livenessProbe
• readinessProbe

REPLICAS:

ideally more than one, or have a PDB that would ensure its running.

• replicas

I guess my questions are:

• Are there any plans to add these?
• Should I knock together a PR?
• Is nats-nack still the correct tool to use for account/stream/consumer management?
• Would you recommend something else?

Happy to accept a PR that sets these defaults 👍

Since Go 1.19 has been I think we can start adding these limits, we also should apply GOMEMLIMIT so that limits.memory actually works for the Go GC.
