Enable Github gh-pages for project ovirt-engine-api-model

[Juan Hernández]

Hello,

In order to have a public and stable location for the documentation of
the API I would like to start using the Github gh-pages mechanism. I
have already created a 'gh-pages' branch in the 'ovirt-engine-api-model'
project, and merged to that branch the first version of the
documentation. The next step is to enable the use of that 'gh-pages'
branch as the source of the documentation in the settins of that
project. But that needs to be done by an administrator of the oVirt
organization. Would you be so kind to do that?

Thanks in advance,
Juan Hernandez
