[VPNaaS] Add support for sha2-384 and sha2-512

[Dongcan Ye]

Currently, VPNaaS plugin limits the ipsec and ike auth algorithm to "sha1" and "sha256", if user add a new driver (for example, hardware vpn gateway), and the new driver supports more auth algorithm, such as "sha2-384", "sha2-512", it can not integrated with current VPNaaS plugin.

In VPNaaS side, we had sumbitted a bug[1] and patchset[2]. We also needs to add those auth algorithms in neutron-client side.
