------------------------------------------------------------
Patch 001 implements:
# Use jline for cli terminal emulation.
# Moved SPNEGO token generator to YarnClientUtils.
# Implemented SPNEGO token header for web socket authentication.
# Implemented client side web socket handling to jline virtual terminal.
# Implemented usage screen for container -shell option.
{code}
yarn container -shell <container-id>
{code}
I am using Jline 3 to emulate terminal IO streams. Jline 3 is converted to BSD
license, hence it becomes possible to be included in Hadoop.
