Proposal / RFE

When running in CRD-backed IPAM mode, the agent does not start its DNS proxy until after it has acquired IP addresses. The DNS proxy should be able to start before this happens.

Is your feature request related to a problem?
The motivation here is primarily for situations in which the agent restarts. Existing endpoints relying on the DNS proxy will lose connectivity until the agent has acquired IPs and started the DNS proxy. Those existing endpoints already have IPs and just need the DNS proxy to be back online in order for them to egress normally.

Describe the solution you'd like
The DNS proxy is started without blocking on the agent acquiring IP addresses.
