[Issue #1543] Update opportunity factories to use more varied data

Summary

Fixes #1543

Time to review: 5 mins

Changes proposed

Updated our factories to generate more varied data in several important fields

Updated the relationship setup for the link tables to make usage of them simpler

Context for reviewers

The additional info section shows some example data generated before & after this change to help showcase it.

While some of our data was pretty varied before, there were a lot of key fields that just looked too static whenever we demoed it. For example, previously every single opportunity title was Research into <job> industry which made the example search results look off. This approach adds quite a bit more variety and sets us up to easily add even more if desired.

This is mostly done by creating a new faker "Provider" in which I implemented several of our fields as functions. These functions can do the following:

1. Choose from a set of pre-defined patterns
2. Automatically set integer/character values
3. Automatically call other providers to get their configured values

With this approach, we can add a lot more variety with minimal additional effort.

@rylew1 / @andycochran - FYI updating the factories so that we don't generate the US-ABC agencies anymore. Should align with actual values

[rylew1]

Thanks - looks like this matches some of the choices we already have on the agency filter. 🚀

Longer term nits since already approved this pr:

• Would you eventually pull all the actual values or define a type or enum?

[chouinar]

I'm not sure how we'll manage Agency long-term in the API. But when the front-end has more agencies in its list, we can add a bunch more here uneventfully regardless of approach.

Looks good! 🚀
