resolve version problem with marshmallow-pagination

[jason-upchurch]

Summary

We use git+https://github.com/jmcarp/marshmallow-pagination@master in requirements.txt. This library does not appear to be maintained, e.g., jmcarp/marshmallow-pagination#3, and currently the versioning requires [email protected] while we use [email protected].

Problem

The above limits use of automated tools such as pip-compile to produce requirements.txt which includes transitive dependencies. In addition, running pipeptree produces:

* marshmallow-pagination==0.1.1
 - marshmallow-sqlalchemy [required: ==0.4.1, installed: 0.15.0]

some options to avoid the errors and increase our ability to use automated tools are:

1. fork marshmallow-pagination and maintain
2. rewrite or find alternative libraries to replace the functionality afforded by marshmallow-pagination

[jason-upchurch]

As a test, I've added https://github.com/jason-upchurch/marshmallow-pagination and bumped version of marshmallow-paginationto reflect addition of [email protected]. Submitted PR to @jmcarp but we may need to maintain this ourselves so that we can use tools such as pipdeptree without seeing warning and pip-tools for transitive dependency management.
