DEP 016

Rename of ensure attribute to package_ensure

This will be in the following classes:

• cassandra::opscenter
• cassandra::optutils

Change code that looks like this:

class { 'cassandra::opscenter':
  ensure => $opscenter_version,
  ...
}

class { 'cassandra::optutils':
  ensure => $optutils_version,
  ...
}

To this:

class { 'cassandra::opscenter':
  package_ensure => $opscenter_version,
  ...
}

class { 'cassandra::optutils':
  package_ensure => $optutils_version,
  ...
}
