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

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.

DataSourceSmartOS: reconfigure network on each boot

In typical cases, SmartOS does not use DHCP for network configuration.
As such, if the network configuration changes that is reflected in
metadata and will be picked up during the next boot.

Add config for ssh-key import and consuming user-data

This patch enables control over SSH public-key import and
discarding supplied user-data (both disabled by default).

  allow-userdata: false
    allow_public_ssh_keys: false

This feature enables closed appliances to prevent customers
from unintentionally breaking the appliance which were
not designed for user interaction.

The downstream change for this is here:

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

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

cc_puppet: Implement csr_attributes.yaml support

This change adds two new parameters:
* csr_attributes
* csr_attributes_path

Those parameters allow to configure the content of the
csr_attributes.yaml file.

cloud-init.service: on centos/fedora/redhat wait on NetworkManager.service

In Centos/RHEL 8, NetworkManager is installed as the networking service.
cloud-init.service needs to run After this service to allow the OS to
bring networking up first.

azure: Do not lock user on instance id change

After initial boot ovf-env.xml is copied to agent dir
(/var/lib/waagent/) with REDACTED password.
On subsequent boots DataSourceAzure loads with a configuration where the
user specified in /var/lib/waagent/ovf-env.xml is locked.
If instance id changes, cc_users_groups action will lock the user.

Fix this behavior by not locking the user if its password is REDACTED.

net/netplan: use ipv6-mtu key for specifying ipv6 mtu values

netplan introduced an 'info' subcommand which emits yaml describing
implemented features that indicate new or changed fields and values
in the yaml that it accepts. Previously, cloud-init emitted the key
'mtu6' for ipv6 MTU values. This is not correct and netplan will
fail to parse these values. Netplan as of 0.98 supports both the
info subcommand and the ipv6-mtu key.

This branch modifies the netplan renderer to collect the netplan
info output into a 'features' property which is a list of available
feature flags which the renderer can use to modify its output. If
the command is not available, no feature flags are set and
cloud-init will render IPv6 MTU values just as MTU for the subnet.

provided by cloudinit.safeyaml. Also, change/move
