Description

oozie.authentication.signature.secret is currently set to oozie by default, which is a pretty poor value for this. We should set it to be random by default (i.e. blank in oozie-site/default).

We should also make it so that with Oozie HA, we store this value in ZooKeeper so all Oozie servers can use the same secret. This may get a little tricky because hadoop-auth's AuthenticationFilter doesn't make it easy/practical to change how the Signer and secret are set. We'll likely have to have Oozie's AuthFilter compute it's own random secret and do all the ZK stuff and set the value of oozie.authentication.signature.secret before calling AuthenticationFilter#init
