[FFe] upgrade to php-opencloud 2.0.0

[Nish Aravamudan]

The v1 version of the opencloud SDK depends on php-guzzle support, which I would like to remove from the archive. v2 of the SDK is in the RC process and depends on the more current php-guzzlehttp (already packaged for Ubuntu).

License: Unsure
Notes: If we decided to not update php-opencloud and aws-sdk-for-php (the former seems riskier), then we would need to do some work to bootstrap php-guzzle properly.

this did not make it before feature freeze, so would need an FFe.

Feature Freeze Exception justification: php-opencloud 1.16.0 (currently in Xenial/universe) does not support PHP7.0 and relies on php-guzzle (deprecated and removed in Xenial). Upstream PHP7.0 support is targeted for 2.0.0 (currently at 2.0.0-RC3). Upstream maintainers are actively driving towards a 2.0.0 full release by next week. The goal for Xenial is to move to PHP7.0 only (ref: https://github.com/rackspace/php-opencloud/issues/655 and https://github.com/php-opencloud/openstack/issues/39).

I'm not exactly sure how to provide an appropriate diff of the upstream changelog, as the project has moved from https://github.com/rackspace/php-opencloud to https://github.com/php-opencloud/openstack.

Will attach the other requested files.

I built the above using an orig.tar.gz generated from https://github.com/php-opencloud/openstack at cd025451.

The tests require the fix at https://github.com/php-opencloud/openstack/pull/41.

The debian tarball is attached.

The above built package does pass its own tests, as evidence in the build log.

[Nish Aravamudan (nacc)]

Ah, there is a bug in the control file (forgot to update bin dep to guzzlehttp and add a pkg-php-tools-overrides file). Rebuilding and testing now.

[Nish Aravamudan (nacc)]

All tests during build and autopkgtests successfully build with this version.

[Steve Langasek (vorlon)]

The existing php-opencloud package in xenial is uninstallable because of its dependency of the removed php-guzzle. So this is definitely an update-or-remove scenario, which is adequate justification for an FFe. FFe granted, will sponsor shortly.

[Steve Langasek (vorlon)]

one problem, generating the upstream tarball with git archive gives me a package that has this lintian error:

E: php-opencloud source: source-is-missing doc/_templates/sphinx_rtd_theme/static/js/modernizr.min.js

This file already exists in the old version of the source, but for some reason lintian doesn't complain about it there. Please investigate the cause of this error.

[Steve Langasek (vorlon)]

Bear in mind that removing the leaf package php-opencloud instead of fixing this issue is still a viable solution for 16.04, and letting Debian sort it out for 16.10.
