Bug description:
  ** description still being worked on, not done yet **

  [IMPACT]
  Most recent version of ubuntu-advantage-tool on github includes fips and livepatch enablement. The fips enablement will allow customers to easily install and configure Canonical's FIPS certified modules on xenial, whereas livepatch allows xenial and trusty customers to patch the running kernel without a reboot.

  This SRU will cover both new features.

  In addition to the new features themselves, a new "status" command was
  added that will give a short summary about the available modules and
  their status, at a glance.

  Note: FIPS certified modules are only available for xenial. Livepatch
  is supported on xenial and trusty. The tool will refuse to enable
  either service on an unsupported ubuntu release.

  Without this updated package, customers of those services have to
  enable them manually by following a series of steps.

  [FIPS DESCRIPTION]
  When "ubuntu-advantage enable-fips <token>" is issued from commandline,

   - configure the private PPA where the FIPS modules are located
   - install the FIPS modules from this PPA to the local machine from where the script is run
   - configure the bootloader to enable fips

  Upon successful completion of these steps, the customer then gets a message stating to reboot
  the machine to complete the fips enablement process.

  Without the script, customers must perform the steps manually.

  [LIVEPATCH DESCRIPTION]
  Livepatch allows customers to apply kernel patches to a running system without rebooting it.

  The current instructions live in http://ubuntu.com/livepatch and boil down to:
  - install snapd if it's not installed already. On trusty this means a new kernel as well.
  - install the canonical-livepatch snap
  - obtain a livepatch token from Canonical
  - run the enable command with the given token

  The ubuntu-advantage-tools package simplifies this process by just
  requesting the token and performing all the other steps on behalf of
  the user. It also conveniently checks the running kernel and instructs
  the user to reboot into a newer kernel if needed to finish the
  installation (this is the case when running trusty).

  [FIX]

  Add fips and livepatch support to the ubuntu-adadvantage-tools
  package. See debdiff below.

  [LIVEPATCH TESTCASES]

  TRUSTY
  0. Install the new ubuntu-advantage-tools package to add livepatch support.

  1. Collect status before enabling livepatch

  type on commandline:
      ubuntu-advantage status

  expect:
  livepatch: disabled

  esm: disabled (not available)

  fips: disabled (not available)

  2. Enable livepatch

  visit https://ubuntu.com/livepatch and obtain a token

  type on commandline,
      sudo ubuntu-advantage enable-livepatch <yourtoken>

  You may be required to install a newer kernel. In that case, expect the
  following output:
  	Installing missing dependency snapd... OK
  	Installing the canonical-livepatch snap.
  	This may take a few minutes depending on your bandwidth.
  	canonical-livepatch 7.24 from 'canonical' installed

  	Your currently running kernel (3.13.0-133-generic) is too old to
  	support snaps. Version 4.4.0 or higher is needed.

  	Please reboot your system into a supported kernel version
  	and run the following command one more time to complete the
  	installation:

          sudo ubuntu-advantage enable-livepatch <yourtoken>

  Once you reboot and re-run the specified command, expect:
  	Enabling Livepatch with the given token, stand by...
  	Successfully enabled device. Using machine-token: <sometoken>
  	Use "canonical-livepatch status" to verify current patch status.

  
  3. Verify livepatch status

  type on commandline,
      ubuntu-advantage status

  expect an output like the following,
  	livepatch: enabled
  	  client-version: "7.23"
  	  architecture: x86_64
  	  cpu-model: Intel Core Processor (Skylake)
  	  last-check: 2017-10-23T15:10:45.640938255Z
  	  boot-time: 2017-10-23T15:10:13Z
  	  uptime: 1m19s
  	  status:
  	  - kernel: 4.4.0-97.120~14.04.1-generic
  	    running: true
  	    livepatch:
  	      checkState: checked
  	      patchState: nothing-to-apply
  	      version: ""
  	      fixes: ""

          esm: disabled (not available)

  [REGRESSION POTENTIAL]
  The current ubuntu-advantage-tools package in trusty, xenial and zesty is basically a NOOP because the only service it supports is ESM, which is only available for precise.
  This update adds two new features to the package: FIPS (xenial only) and Livepatch (trusty and xenial), essentially making the package useful in trusty and xenial. For zesty there is no change, as none of these products are available for non-LTS releases.

  [OTHER INFO]
  The way this package was made available in all the ubuntu releases where it is now was via a "pocket copy". That's why it has the exact same version in trusty, xenial and zesty. Currently artful has version 10 (a version 12 just missed the feature freeze), so in order for upgrades between releases to work, we adopted the backports versioning scheme, by appending the ubuntu release code with a tilda ("~") to the version.
  Another point is that even though ubuntu-advantage-tools is "just" a shell script, it is unit tested with python3, and these tests (and lint runs) gate merges in the upstream github repository at github.com/CanonicalLtd/ubuntu-advantage-script/
