Issue 51: Method for renewing Instructional Computing Allowances (ICAs)

[adeng27]

Based off code from @matthew-li

• This PR contains updated projects command-line tool (coldfront.core.project.management.commands.projects) to enable renewal of ICA projects that have the "Inactive" status.
  • Added a subcommand renew by which this can be done.
    • It takes arguments: the name of the Project, the username of the User making the request, and the name of the AllocationPeriod the allowance will be valid for.
    • It will approve and process the request. I will provide you with some example code I've run manually in the past that should be adapted into this command.
    • Disallow renewals of other project types at this point (so only ICAs).
    • There should be a dry_run flag (see the create subcommand).

Assumptions made:

• I assumed that the pre-project and post-project referred to the same project (namely, the inputed project).
• The requester must be a part of the project or else a CommandError will be raised.
• The allocation period must be currently occurring or else a CommandError will be raised.

• I've done some refactoring to generalize this for renewing yearly allowances, and avoid duplicating logic.
• I've also added some additional constraints to the command (e.g., the requester must be a manager or PI).
• I've left some comments in test_commands.test_projects.TestProjectsRenew describing some additional test cases that should be added. Can you fill those in?
• Lastly, I noted in the command that we need to prevent a request from being made if the PI isn't "allowed" to have one: this is based on whether they already have a renewal request or new project request, etc. I've been working on refactoring the logic needed for this check into a class, and will fill this in.

• Disallowed renewals of allowances that are one per PI until the business logic has been implemented (later).
• Added and fixed some tests.
