    Add parameters for vTPM feature
    
    Add a single new parameter, NovaEnableVTPM, which will configure vTPM
    support by setting nova's '[libvirt] swtpm_enabled' config option. We do
    not yet expose nova's '[libvirt] swtpm_user' and '[libvirt] swtpm_group'
    options since the Fedora RPM specfile, upon which CentOS' and RHEL's
    specfiles are based, uses the standard user and group [1].
