Google storage push is broken

[tschoonj]

Describe the bug

Trying to upload an image to a google storage bucket does not work with httplib2 >= 0.16.0 due to changes introduced in that version that are currently not handled by the google-api-client-api library.

What currently happens is a 'hanging' upload due to an exception being thrown:

which is caught by the retry call, so had to remove the decorator to actually get this far 😄

To Reproduce
Steps to reproduce the behavior: install sregistry with google-storage backend support using the latest versions of all required dependencies.

This may also affect other (google-) backends but I haven't tested this.

Version of Singularity and Singularity Registry Client
sregistry-client: 0.2.33

Anything else?

Should we pin the version of httplib2 in the conda repo to <= 0.15.0 until the google-api-client library contains a fix?

[vsoch]

Yes pinning the version to what previously worked is a good bet for now. I’d be happy to review a PR for this.

[vsoch]

Fixed with #253

[tschoonj]

This is fixed upstream now, may be useful to change pinning here, and revert the corresponding PR.

[vsoch]

@tschoonj that's a good idea - revert would remove all the commits done for that PR (which I don't think we want to do) but if you have bandwidth in the next few weeks, do you want to open a simple PR to bump the version and change pinning? We could then update the conda force recipe to match.

First thing tomorrow morning!

Woot! Thanks @tschoonj !
