Some Singularity-python bugs with Python 2.7

[victorsndvg]

Hi all,

I'm trying to use the development branch of vsoch/singularity-python with sregistry and I'm getting some errors.

I would like to post this directly in the right repository, please @vsoch, could you open the issues feature for this repository? If not, which communication channel do you prefer to post issues about this repository?

I'm running run_client.sh example and I have Python 2.7.12 installed. is Python 3 a requirement?

Lets go with the bugs,

• First, in this line, L86 It crashes because image does not exist.
• Then, Calling to $ sregistry list $IMAGE with an existing image, I get the following error with the date:

...
  File "/usr/local/lib/python2.7/dist-packages/singularity-1.2.0-py2.7.egg/singularity/registry/client/query.py", line 213, in container_search
    datetime_object = datetime.strptime(c['add_date'], '%Y-%m-%dT%H:%M:%S.%fZ')
ValueError: time data '2017-10-13T01:47:50.824098-05:00' does not match format '%Y-%m-%dT%H:%M:%S.%fZ'

• There is another error calling to: $ sregistry delete $IMAGE

This line crashes [L54](https://github.com/vsoch/singularity-python/blob/development/singularity/registry/client/delete.py#L54) . It seems that python 3 `input` command equivalent in python 2.5 is `raw_input` . 
* Finally,  if I try to force-delete `$ sregistry delete --force $IMAGE` It returns:

ERROR Beep boop! Internal Server Error: 500

Thanks in advance!

You are correct that I have done absolutely no testing for python 2.x. Please file all the issues and we will fix them up!
