RFR: 8225181: KeyStore should have a getAttributes method [v5]

[Michael StJohns]

Hi -

Generically, PKCS12 doesn't require an alias (friendlyName) for a 
particular Bag, but does permit it. Which means that 
getAttributes(String alias) could fail on a legal PKCS12.  It may be 
worthwhile to add a Set<Entry.Attribute> KeyStore::getAttributes(int 
bagNumber) method.
