Deprecate code for classical provisioning mode

[Vitaly Parakhin]

In Fuel 7.0 we dropped classical provisioning mode, fully switching to IBP.
We need to investigate, and finally get rid of all related code:

1) placeholders for cobbler Ubuntu profile in fuel-main
2) the fuel-provisioning-scripts package in fuel-web

    Remove debian-installer placeholders

    In Fuel 7.0 we dropped classical provisioning mode,
    fully switching to IBP. Since then, placeholders
    created for Ubuntu cobbler profile, are no longer
    needed. Also, remove 'fuel' package dependency for
    the 'fuel-provisioning-scripts' which contains
    debian-installer download script.

    Remove deprecated cobbler parts for classic provisioning

    Since Fuel 6.1 we no longer support CentOS envs,
    so let's remove related cobbler config entries,
    snippets etc.
    In Fuel 7.0 we dropped classic provisioning mode,
    fully switching to IBP. Remove cobbler distro and
    profile for debian-installer, since it's no longer
    used [1]
