LG-10195

🛠 Summary of changes

Add a boolean second_address_line_present parameter to the 'USPS IPPaaS enrollment created' event that is true when the user has entered a second address line.

📜 Testing Plan

1. Go through the IPP flow, create an enrollment
2. Check the log for a 'USPS IPPaaS enrollment created' event
3. The second_address_line_present parameter on the event should be true if you entered a second address line, and false otherwise. Check different DAV configurations:
   1. DAV false, address line 2 present/missing in current address
   2. DAV true, address line 2 present in state ID address, state ID matches residential
   3. DAV true, address line 2 present in state ID address, state ID doesn't match residential, address line 2 missing from residential address

this reuses the existing address2, right? What if we added a new, unused address so we can make sure it's checking the correct address2?

[tomas-nava]

We're checking the presence rather than the content of address2, so I don't think we need to worry about that (if I'm interpreting your comment correctly). When I was looking closer at the test, though, I decided to remove this constant and set values in the tests themselves instead, that's in 012477e
