DocumentEntryPoints in Treasuremap are coupled to site names since the
documents have not been updated to leverage the docEntryPointPrefix
feature. This change enables the feature in order to de-couple phase
documentEntryPoints from site paths, improving downstream consumption of
these documents.
Closes #49
