feat: make status histogram buckets configurable

Issue #, if available:

Description of changes:

Following breadcrumbs from Karpenter.

We are drilling into attributing costs to the lifecycle of Nodes (EC2 instances) within our platform. The Karpenter project uses awslabs/operatorpkg to emit metrics on status condition changes for CRDs like NodeClaim and NodePool - exactly what we are after.

Unfortunately, these metrics are emitted as histograms with non configurable buckets (defaults to prometheus.DefBuckets). As objects like NodeClaim can take seconds to many minutes (or longer) to transition state, the default max bucket of 5seconds makes these metrics less useful.

This PR allows consumers to optionally configure the histogram metrics buckets, keeping the existing default behavior.

Thanks @jonathan-innis - is there anything extra needed to pass the presubmit verification? I'll open up the other Karpenter related PR's once this is merged.
