DataSourceSmartOS: add locking of serial device.

cloud-init and mdata-get each have their own implementation of the
SmartOS metadata protocol. If cloud-init and other services that call
mdata-get are run concurrently, crosstalk on the serial port can cause
them both to become confused.

This change makes it so that cloud-init uses the same cooperative
locking scheme that's used by mdata-get, thus preventing cross-talk
between mdata-get and cloud-init.

For testing, a VM running on a SmartOS host and pyserial are required.
If the tests are run on a platform other than SmartOS, those that use a
real serial port are skipped. pyserial remains commented in
requirements.txt because most testers will not be running atop SmartOS.

DataSourceSmartOS: sdc:hostname is ignored

There are three potential sources of the hostname, one of which is
documented SmartOS's vmadm(1M) via the hostname property. That
property's value is retrieved via the sdc:hostname key. The other
two sources for the hostname are a hostname key in customer_metadata
and the VM's uuid (sdc:uuid). Of these three, the sdc:hostname value
is not used in a meaningful way by DataSourceSmartOS.

This fix changes the fallback mechanism when hostname is not
specified in customer_metadata. The order of precedence for setting
the hostname is now 1) hostname in customer_metadata,
2) sdc:hostname, then 3) sdc:uuid.

DataSourceSmartOS: list() should always return a list

If customer_metadata has no keys, the KEYS request returns an empty
string. Callers of the list() method expect a list to be returned and
will give a stack trace if this expectation is not met.

schema: in validation, raise ImportError if strict but no jsonschema.

validate_cloudconfig_schema with strict=True would not actually validate
if there was no jsonschema available. That seems kind of strange.
The change here is to make it raise an exception if strict was passed in.
And then to fix the one test that needed a skipIfJsonSchema wrapper.

set_passwords: Add newline to end of sshd config, only restart if updated.

This admittedly does a fairly extensive re-factor to simply add a newline
to the end of sshd_config.

It makes the ssh_config updating portion of set_passwords more testable
and adds tests for that.

The new function is in 'update_ssh_config_lines' which allows you
to update a config with multiple changes even though only a single one
is currently used.

We also only restart the ssh daemon now if a change was made to the
config file. Before it was always restarted if the user specified
a value for ssh_pwauth other than 'unchanged'.

Thanks to Lorens Kockum for initial diagnosis and patch.

pylint: pay attention to unused variable warnings.

This enables warnings produced by pylint for unused variables (W0612),
and fixes the existing errors.

Schema: do not warn on duplicate items in commands.

runcmd, bootcmd, snap/commands, ubuntu-advantage/commands would
log warning (and fail if strict) on duplicate values in the commands.
But those should be allowed. Example, it is perfectly valid to do:
   runcmd: ['sleep 1', 'sleep 1']

net: Depend on iproute2's ip instead of net-tools ifconfig or route

The net-tools package is deprecated and will eventually be dropped. Use
"ip route", "link" or "address" instead of "ifconfig" or "route" calls.
Cloud-init can now run in an environment that no longer has net-tools.
This affects the network and route printing emitted to
cloud-config-output.log as well as the cc_disable_ec2_metadata module.

Additional changes:
 - separate readResource and resourceLocation into standalone test
 - Fix ipv4 address rows to report scopes represented by ip addr show
 - Formatted route/address ouput now handles multiple ipv4 and ipv6
   addresses on a single interface
