mellon 0.18+ does not work on chromium-based browsers

[Rodrigo Barbieri]

Since commit [1] mellon changed the default behavior of cross-site cookies by allowing all if unset.

Some IDP providers use cross-site cookies to authenticate. Chromium-based browsers reject insecure cross-site cookies.

It is necessary to add the following parameters to mellon apache config file so it can use secure HTTPS cookies to be compatible with chromium-based browsers:

MellonSecureCookie On
MellonCookieSameSite None

I assigned you, Rodrigo, to the bug as you created the review. Hope that's okay.

[Rodrigo Barbieri (rodrigo-barbieri2010)]

Thanks Alex! Apparently the Closes-bug gerrit tag didn't do its job this time.
