[beeswax] Rename error to info
[beeswax] Close Beeswax queries
[beeswax] Close query for any type of queries
[beeswax] Cleared all old references to Beeswax daemon
[impala] Close queries commands cannot work for Impala

For technical reasons, Impala connections happens at the network level
so for closing them we should run the command from a view on the
webserver.

[jb] Also show jobs according to acl modify permissions

e.g.
set mapreduce.job.acl-modify-job=UserA; : kill job
[jb] Also show jobs according to acl view permissions

e.g.
set mapreduce.job.acl-view-job=UserA;

Note: this only work when going directly to the single job page:
The job will still not appear on the main list of jobs (MR1/MR2
APIs do not allow a batch check of the acl permissions).
[jb] Basic test with mocking for view and modify acl and MR1
