This class implements a Cacheable for a DataDictionary cache of
sps descriptors, with the lookup key being the name/schema of the sps.
Assumes client passes in a string that includes the schema name.
The cache ensures that the class of the target sps is loaded
if the sps is found in cache.
Factory for creating a SYSALIASES row.
Here are the directions for adding a new system supplied alias.
Misc:
All system supplied aliases are class aliases at this point.
Additional arrays will need to be added if we supply system
aliases of other types.
The preloadAliasIDs array is an array of hard coded UUIDs
for the system supplied aliases.
The preloadAliases array is the array of aliases
for the system supplied aliases.
