  KernelRemoval section is out of date

Bug description:
  The dist-upgrader tarball includes configuration files for the release
  upgrade process and part of the configuration file is a section with
  the heading KernelRemoval which includes Version, BaseNames, and Types
  which are used to build a list of kernels to remove. This section has
  not been updated in quite some time and we should up date so systems
  have less old kernels installed.

  [Test Case]
  1) upgrade a system from a release of Ubuntu to a new release of Ubuntu (this should be done for the following paths B->C, C->D, B->D)
  2) observe the following in /var/log/dist-upgrade/main.log
  "2019-05-07 11:38:23,264 DEBUG identifyObsoleteKernels()
  2019-05-07 11:38:27,621 DEBUG identifyObsoleteKernels found 'set()'"

  The release upgrader from -proposed (do-release-upgrader -p) should
  identify some obsolete kernels ("skipping running kernel linux-
  headers-5.0.0-13-generic") even if it doesn't end up removing them.

  [Regression Potential]
  I made the BaseNames section split out across multiple lines which should be fine but that could cause the config file to fail to be parsed which would probably cause a crash or the same failure to remove obsolete kernels.
