Investigate Performance of bpfman agent

[anfredette]

We've seen the sample BpfApplication CRD take ~30 seconds to finish loading its eBPF programs. A look at the agent log suggests that this biggest factor is the call to bpfman to load the programs, which appears to take from 2-12 seconds. So, while this issue is being written against bpfman-operator, I believe that the first place to look is in the bpfman load path.

Some likely suspects are the image pull from podman and cosign validation, but this needs to be confirmed.
