Add support for content-based load balancing to HealthCheck

[rileykarson]

Ha! The diff got a little confused here; the "real" change is to move response into all 4 types of HealthCheck by moving it out of the conditional. It was previously only available for TCP & SSL.

TF downstream look ok. Cc'ed @rambleraptor to look at the ansible one.

Ansible looks fine! I'm super confused by the diff for MM though.

Git's behaviour makes sense here! It's just a little unintuitive, and happened because either change was +- 5 lines. It probably chose this one because it was less characters moving.

It sees the text changing, but doesn't know how I made that change.

a
b
c

became

b
a
c

It can represent that as the smallest possible diff with either diff:

-a
b
+a
c

or

+b
a
-b
c
