AzureException always raised as KeyError

[monika-moeddel-by]

Hi, when trying to put a file to an azure blob storage

store.put_file('myfile.txt','myfile.txt')

this confusing KeyError was returned: File "...lib/python2.7/site-packages/simplekv/__init__.py", line 177, in put_file return self._put_filename(key, file) File "...lib/python2.7/site-packages/simplekv/net/azurestore.py", line 123, in _put_filename return key File "/usr/lib/python2.7/contextlib.py", line 35, in __exit__ self.gen.throw(type, value, traceback) File "...lib/python2.7/site-packages/simplekv/net/azurestore.py", line 38, in map_azure_exceptions raise KeyError(key) KeyError: 'myfile.txt'

In this case the cause was a missing internet connecting. Could you please consider to improve the exception handling and not raise all AzureException as KeyError.

It looks like in this case the exception handling suppresses important information. I will try to come up with a patch.
