org.das2.util.filesystem.KeyChain

class that contains the credentials for websites. This is first introduced so that ftp://papco:@mrfrench.lanl.gov/ and subdirectories would just ask for credentials once. Also, this allows all the sensitive information to be stored in one class. https://datatracker.ietf.org/doc/html/rfc7617 talks about how this should be done. Presently this is done by URL and not the realm. TODO: This needs to be redone so that the keys are stored by realm as well, and once a directory is left a 401 and resending of the realm will be needed before the key is sent again.
