containerregistry in Pypi

[jinchihe]

containerregistry v0 in Pypi is created by @mattmoor and containerregistry-ccwienk is created by @ccwienk, seem the containerregistry v0 is not updated, and containerregistry-ccwienk now v0.2.3. Any plan to update containerregistry or containerregistry-ccwienk?

But there are some strict requirements for containerregistry-ccwienk package as below.

httplib2<0.13,>=0.11.3
futures<3.2,>=3.1.1
six<1.13,>=1.9
rsa>=3.1.4

is that possiable to relax restrictions the requirements to get rid of the "<" as below

httplib2>=0.11.3
futures>=3.1.1
six>=1.9
rsa>=3.1.4
