Add filtering for IPsec algorithms in IKEv2 VPNs
This commit adds support for validating and filtering IPsec algorithms.
Without a public API exposing IKEv2 algorithms (and their respective
public APIs), the allowedAlgorithms can only filter the proposals for
IPsec (Child) SA algorithms.
Additionally, this removes the HMAC_SHA1 from the IKE SA's integrity
algorithm proposals due to insecurity
