|initial_security_level| used to be the way that ChromeSSMClient provided the
SSLStatus::security_style to SSM, and SSM used that as a baseline starting point
for computing the SecurityLevel. This isn't needed anymore; SSM just calculates
the baseline starting point itself instead of taking it from
SSLStatus::security_style.

I prefer the new way, I find it more self explanatory
