create ConnectionState before adding to HostMap (#535)
We have a few small race conditions with creating the HostInfo.ConnectionState
since we add the host info to the pendingHostMap before we set this
field. We can make everything a lot easier if we just add an "init"
function so that we can set this field in the hostinfo before we add it
to the hostmap.

remote_allow_ranges: allow inside CIDR specific remote_allow_lists (#540)
This allows you to configure remote allow lists specific to different
subnets of the inside CIDR. Example:

    remote_allow_ranges:
      10.42.42.0/24:
        192.168.0.0/16: true

This would only allow hosts with a VPN IP in the 10.42.42.0/24 range to
have private IPs (and thus don't connect over public IPs).

The PR also refactors AllowList into RemoteAllowList and LocalAllowList to make it clearer which methods are allowed on which allow list.

refactor: use X25519 instead of ScalarBaseMult (#533)
As suggested in https://pkg.go.dev/golang.org/x/crypto/curve25519#ScalarBaseMult,
use X25519 instead of ScalarBaseMult. When using Basepoint, it may employ
some precomputed values, enhancing performance.

Check CA cert and key match in nebula-cert sign (#503)
`func (nc *NebulaCertificate) VerifyPrivateKey(key []byte) error` would
previously return an error even if passed the correct private key for a
CA certificate `nc`.

That function has been updated to support CA certificates, and
nebula-cert now calls it before signing a new certificate. Previously,
it would perform all constraint checks against the CA certificate
provided, take a SHA256 fingerprint of the provided certificate, insert
it into the new node certificate, and then finally sign it with the
mismatching private key provided.

Add more metrics (#450)
* Add more metrics

This change adds the following counter metrics:

Metrics to track packets dropped at the firewall:

    firewall.dropped.local_ip
    firewall.dropped.remote_ip
    firewall.dropped.no_rule

Metrics to track handshakes attempts that have been initiated and ones
that have timed out (ones that have completed are tracked by the
existing "handshakes" histogram).

    handshake_manager.initiated
    handshake_manager.timed_out

Metrics to track when cached_packets are dropped because we run out of
buffer space, and how many are sent once the handshake completes.

    hostinfo.cached_packets.dropped
    hostinfo.cached_packets.sent

This change also notes how many cached packets we have when we log the
final "Handshake received" message for either stage1 for stage2.

* separate incoming/outgoing metrics

* remove "allowed" firewall metrics

We don't need this on the hotpath, they aren't worh it.

* don't need pointers here
