[pkg-php-pear] [PHP7] php-opencloud 2.0.0

[Nish Aravamudan]

FYI, php-opencloud 2.0.0 needs packaging for PHP7 support, but for some
reason at the last moment the upstream broke out their common layer to
another repository, so that will probably necessitate introducing
php-opencloud-common. I was able to get the latter to build via `gbp
clone`, but am having trouble introducing the dependency with the former.
