Title:
  [SRU][xenial] include recent version containing fips and livepatch

Status in ubuntu-advantage-tools package in Ubuntu:
  Fix Released
Status in ubuntu-advantage-tools source package in Xenial:
  New
Status in ubuntu-advantage-tools source package in Zesty:
  New

Bug description:
  [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 customers to patch the kernel without a reboot.

  This SRU will cover both new features.

  Note: FIPS certified modules and livepatch are only available for
  xenial. On other releases the tool will not install and configure fips
  or livepatch.

  [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]
  TBW

  [FIX]

  Add enable-fips to advantage script. See debdiff below.

  [TEST]
  A test package is available: and it was tested by me on S390, PPC64EL and AMD64 architectures.

  [REGRESSION POTENTIAL]
  The patch adds a new features to ubuntu-advantage-tool in Xenial to enable fips and livepatch. Current functionality was not altered.

  [FIPS TESTCASES]
  These testcases assume you have installed ubuntu-advantage-tools with the proposed changes.
