## Problem
Not all cplane errors are properly recognized and cached/retried.
## Summary of changes
Add more cplane error reasons. Also, use retry_delay_ms as cache TTL if
present.

For TLS between proxy and compute, we are using an internally
provisioned CA to sign the compute certificates. This change ensures
that proxy will load them from a supplied env var pointing to the
correct file - this file and env var will be configured later, using a
kubernetes secret.
Control plane responds with a `server_name` field if and only if the
compute uses TLS. This server name is the name we use to validate the
certificate. Control plane still sends us the IP to connect to as well
(to support overlay IP).
To support this change, I'd had to split `host` and `host_addr` into
separate fields. Using `host_addr` and bypassing `lookup_addr` if
possible (which is what happens in production). `host` then is only used
for the TLS connection.
There's no blocker to merging this. The code paths will not be triggered
until the new control plane is deployed and the `enableTLS` compute flag
is enabled on a project.
- Wired up filtering on VPC endpoints
- Wired up block access from public internet / VPC depending on per
project flag
- Added cache invalidation for VPC endpoints (partially based on PR from
Raphael)
- Removed BackendIpAllowlist trait

## Problem
Now that https://github.com/neondatabase/cloud/issues/15245 is done, we
can remove the old code.
## Summary of changes
Removes support for the ManagementV2 API, in favour of the ProxyV1 API.
The overall idea of the PR is to rename a few types to make their
purpose more clear, reduce abstraction where not needed, and move types
to to more better suited modules.
