Renames some DomainState functions for increased clarity. 

Updates consumers of DomainState to rely on these functions 
instead of relying on GetDomainState() returning true indicating 
HSTS semantics, as this would likely become a problem later on 
(eg: as DomainState is extended to store non-HSTS data like 
HPKP or TACK)
