include hbase client libraries to oozie's libext, and enable hbase delegation for oozie workflows

[pu239ppy]

This will allow to run hbase commands and applications from oozie, whithout having to kinit and store passwords or deploy keytabs
Basing on #381, few changes to layout and ensuring that there is no version dependency

[pu239ppy]

Was able to execute a simple ruby script with hbase shell

Stdoutput ubuntu (auth:KERBEROS)
Stdoutput     groups: ubuntu, adm, dialout, cdrom, sudo, plugdev, lpadmin, sambashare
Stdoutput
Stdoutput ROW  COLUMN+CELL
Stdoutput  r1 column=cf1:c1, timestamp=1475181412320, value=v1
Stdoutput 1 row(s) in 0.3620 seconds
Stdoutput
Exit code of the Shell command 0

Sample configuration
in hbase shell

grant 'ubuntu', 'RWCAX'

X is needed for delegation tokens

job.properties.txt
sampleworkflow.txt

whoami.rb

whoami
scan 't1'
exit

Steps for creation of t1 can be found in the wiki along with procedures on hbase entitlement assignments

@pu239ppy hbase upgrade seems to be redundant.
