Include detailed landlord information from NYCDB in HP Action packet

This fixes #394.

A note on corporate landlords

I think I made a slight mistake in #380, in that for corporate landlords, I took the "name" value from the company owner field. However, based on the way @romeboards filled out the HP Action form on the LHI website, I think we actually need to take the name from the head officer field (we've been using the address from the head officer field, but not the name).

I think this is because company names are so often hidden behind a shell company that they're rendered fairly useless.

That said, the LHI interactive form makes it seem like you are supposed to put the company name in the "name of landlord" field, because once you select the "company" radio button, the "first name" and "last name" fields (which are shown for individual landlords) disappear and are replaced by a single "name of landlord" field. It seems like the creators of the LHI form were themselves confused, because this snippet shows up in the Master.cmp:

IF Landlord entity or individual MC = "Individual"
    SHOW Landlord name first TE
    SHOW Landlord name last TE
ELSE
    SHOW Landlord entity name TE
    //	SHOW Landlord contact person name first TE
    //	SHOW Landlord contact person name last TE
END IF

Notice the commented-out lines; it seems like at some point, they were asking for a contact person's first and last name in the case of corporate landlords, but reverted to just asking for an "entity name".

This is so confusing.

Caching a user's BBL

We're finally moving to just caching a user's BBL, like we already cache their ZIP code, rather than constantly re-fetching it from the geocoding service whenever we need it. However, this is going to require populating the cached field once we make the database migration that's included in this PR. Here's some code to do that:

import os

if __name__ == '__main__':
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings')

    import django
    django.setup()

    from onboarding.models import OnboardingInfo

    for info in OnboardingInfo.objects.filter(pad_bbl=''):
        print(f"Updating address metadata for {info.user}.")
        info.save()

Um, I say "in practice it doesn't seem to mind" but I haven't actually verified this, I'm just guessing it's the case. I should verify it before merging.

Okay, I just verified it... um... it actually seems like the more granular address info might not be used at all, i.e. LHI is just asking for it so it knows that the full address it pastes together is valid, and it doesn't need to do that with our answers because we paste stuff together on our end. I might be wrong though.

@romeboards I'm curious what you think of this TODO. Do we still want to fill out the fields asking if the management company should be sued, even if we don't find a management company for the user, so that hopefully the forms are in the packet just in case they decide to go that route? Or alternatively, if the user has an individual owner landlord (not a company) does that mean there won't be a management company involved?

@romeboards also curious what you think of this. Since you filled out "home phone" on LHI's site, I'm guessing it's the one we want to fill out for the user.

Heh, the PDF wasn't showing the address of the management company at all until I explicitly added this line. So finicky.
