[Katello] 3.2 to 3.3 upgrade issues

Hi,

Having issues upgrading from 3.2 to 3.3. The server part went OK, but the
smart proxy fails.

Firstly there seems to be a typo in step 2, the URL for the foreman repo is
incorrect, should
be http://yum.theforeman.org/releases/1.14/el7/x86_64/foreman-release.rpm.

Then on step five the foreman-installer command provided gives an error of,
"Parameter certs-regenerate is missing a value on the command line". It's
not listed in the output from --help, but I guessed at a value of "true".
The modified command runs but the process fails with " must be present at
/usr/share/katello-installer-base/modules/foreman_proxy_content/manifests/init.pp:103
on node <redacted>".

I'm assuming this is because I need to provide the oauth keys, but
attempting to provide them just gives "ERROR: too many arguments".

Any pointers on where I've gone wrong?

Thanks,

Alan
