SSH jobs should support elliptic curves (ECDSA) for authentication

Current Situation

• JCraft does not support ECDSA, see http://www.jcraft.com/jsch/

Desired Behavior

• Support for ECDSA is required in JSch and JADE

Targeted Resolution

• The JCraft team has tweeted: https://twitter.com/ymnk/status/570116671899185152

  On our JSch, we have succeed to support #SSH ECC algorithm defined in RFC5656 http://tools.ietf.org/html/rfc5656 ; ecdsa-sha2-* and ecdh-sha2-* methods.

• ECDSA support is available starting from JSch version 0.1.52, see http://www.jcraft.com/jsch/ChangeLog
• We will check if the latest JSch version is compatible with SSH jobs and if the JSch library can be updated to a newer version.
