add redirects stream

[jgdwyer]

Description of change

Adds a new redirects Stream to sync Shopify Online-Store/Redirect data.

Because there are no timestamp properties on the Redirect data, I had to configure it as a full table replication and override the base get_objects function. I used the collects module as a template for this.

QA steps

• automated tests passing
• manual qa steps passing (list below)
  • Running the steps in the makefile individually works (for some reason I was getting an error when running make test)
  • Also got expected redirect data from an existing Shopify store, including when pagination was required.

Risks

• This is my first development work on a tap, so it's possible I messed something up :-)

Rollback steps

• revert this branch
