Add certificate information to Usage Information

Browse Source 
[ Merge of http://go/wvgerrit/120509 ]

Certificates and wrapped key material are stored in the usage information
file but apart from usage information records. Usage info records include
an identifier which indicates the associated certificate. Routines to
help with finding, inserting or removal of associated certificates have
been included. After a usage entry is deleted, a garbage collection
routine is run to remove any certificates not used by usage infomation
records.
