Defines the SiteCacheContext service, for "per site" caching.

Cache context ID: 'url.site'.

A "site" is defined as the combination of URI scheme, domain name, port and base path. It allows for varying between the *same* site being accessed via different entry points. (Different sites in a multisite setup have separate databases.) For example: http://example.com and http://www.example.com.
