[Pki-devel] [PATCH] 625 Fixed fail-over in HttpConnection.

The HttpConnection class has been modified to support fail-over and timeout more consistently. The targets are parsed into a list during initialization. All direct calls to HttpClient.connect() are replaced with a method that will connect to the first available target. All connections are now created with a timeout (which by default is 0). The timeout is handled internally by JSS instead of by explicitly abandoning asynchronous connection thread. https://fedorahosted.org/pki/ticket/891 -- Endi S. Dewata
