CachedSource class abstract
Base class for a BoundSource that installs packages into pub's
SystemCache.
A source should be cached if it requires network access to retrieve packages or the package needs to be "frozen" at the point in time that it's installed. (For example, Git packages are cached because installing from the same repo over time may yield different commits.)
