Problem:
In non-root fail-over/fail-back(FO/FB), when slave is
promoted as master, the session goes to 'Faulty'
Cause:
The command 'gluster-mountbroker <mountbroker-root> <group>'
is run as a pre-requisite on slave in non-root setup.
It modifies the permission and group of following required
directories and files recursively
[1] /var/lib/glusterd/geo-replication
[2] /var/log/glusterfs/geo-replication-slaves
In a normal setup, this is executed on slave node and hence
doing it recursively is not an issue on [1]. But when original
master becomes slave in non-root during FO/FB, it contains
ssh public keys and modifying permissions on them causes
geo-rep to fail with incorrect permissions.
Fix:
Don't do permission change recursively. Fix permissions for
required files.

When 'gluster-mountbroker status' was issued, it
crashes in a corner case with 'str object has not
attribute get'. Fixed the same.

Note 1) we're not supposed to be using #!/usr/bin/env python, see
https://fedoraproject.org/wiki/Packaging:Guidelines?rd=Packaging/Guidelines#Shebang_lines
Note 2) we're also not supposed to be using "!/usr/bin/python,
see https://fedoraproject.org/wiki/Changes/Avoid_usr_bin_python_in_RPM_Build#Quick_Opt-Out
The previous patch (https://review.gluster.org/19767) tried to do too
much in one patch, so it was abandoned.
This patch does two things:
1) minor cleanup of configure(.ac) to explicitly use python2
2) change all the shebang lines to #!/usr/bin/python2 and add them
where they were missing based on warnings emitted during rpmbuild.
In a follow-up patch python2 will eventually be changed to python3.
Before that python2-isms (e.g. print, string.join(), etc.) need to be
converted to python3. Some of those can be rewritten in version agnostic
python. E.g. print statements become print() with "from __future_ import
print_function". The python 2to3 utility will be used for some of those.
Also Aravinda has given guidance in the comments to the first patch for
changes.

Setting up Non root Geo-replication is troublesome. Lot of steps
involved like user setup, directory creation, setting up proper
permissions, editing glusterd.vol file etc.
Introducing `gluster-mountbroker` command, with this tool non root
user setup steps are(Run the following commands in any one Slave
node),
gluster-mountbroker setup <MOUNT ROOT> <GROUP>
For example,
gluster-mountbroker setup /var/mountbroker-root geogroup
Add user using,
gluster-mountbroker add <VOLUME> <USER>
For example,
gluster-mountbroker add slavevol geoaccount
Remove user or Volume using,
gluster-mountbroker remove [--volume <VOLUME>] [--user <USER>]
Example,
gluster-mountbroker remove --volume slavevol --user geoaccount
gluster-mountbroker remove --user geoaccount
gluster-mountbroker remove --volume slavevol
Check the status of setup using,
gluster-mountbroker status
Once the changes are complete, restart glusterd in all Slave nodes.
and follow the Geo-rep instructions.
