When enabling FIPS 140-3 mode with `GODEBUG=gofips=X` on supported platforms, the following restrictions are made to allow NATS to function: 1. `auth_callout` cannot be configured and will error at startup if it is; 2. `chacha` filestore encryption mode cannot be configured and will error at startup if it is; 3. `X25519` is removed from the default curve preferences; 4. TLS handshakes that require non-FIPS-compliant algorithms will fail. Signed-off-by: Neil Twigg <neil@nats.io>
