net: IPv6, accept_ra, slaac, stateless

Router advertisements are required for the default route
to be set up, thus accept_ra should be enabled for
dhcpv6-stateful.

sysconf: IPV6_FORCE_ACCEPT_RA controls accept_ra sysctl.
eni: mode static and mode dhcp 'accept_ra' controls sysctl.

Add 'accept-ra: true|false' parameter to config v1 and
v2. When True: accept_ra is set to '1'. When False:
accept_ra is set to '0'. When not defined in config the
value is left to the operating system default.

This change also extend the IPv6 support to distinguish
between slaac and dhcpv6-stateless. SLAAC is autoconfig
without any options from DHCP, while stateless auto-configures
the address and the uses DHCP for other options.

net: fix subnet_is_ipv6() for stateless|stateful

Function return false for ipv6_dhcpv6-stateless|stateful,
the eni renderer does not add '6' to 'inet' which is
incorrect.

The subnet_is_ipv6() function is updated to also return
true if startswith('ipv6').

net: handle openstack dhcpv6-stateless configuration

Openstack subnets can be configured to use SLAAC by setting
ipv6_address_mode=dhcpv6-stateless. When this is the case
the sysconfig interface configuration should use
IPV6_AUTOCONF=yes and not set DHCPV6C=yes.

This change sets the subnets type property to the full
network['type'] from openstack metadata.

cloudinit/net/sysconfig.py and cloudinit/net/eni.py
are updated to support new subnet types:
  - 'ipv6_dhcpv6-stateless' => IPV6_AUTOCONF=yes
  - 'ipv6_dhcpv6-stateful' => DHCPV6C=yes

Type 'dhcp6' in sysconfig is kept for backward compatibility
with any implementations that set subnet_type == 'dhcp6'.
