Skip DNS lookup the cached remote addresses match the network
This patch changes the default DNS strategies to add more DNS bypass
cases. This behavior changes are gated by a mendel flag. Specifically
the existing cases and newly added cases to skip DNS are as follows:
- When network not changed:
- [EXSITING] the locally supported IP families and cached remote
addresses match
- [NEW] the cached remote addresses are dual stack
- When network changed:
- [NEW] the locally supported IP families and cached remote
addresses match
- [NEW] the cached remote addresses are dual stack
This patch also adds an IKE option that allows a caller to force
DNS lookup.
