METRON-1451: On Centos full dev, Metron Indexing shows up as stopped
## Contributor Comments
**Root Cause**
The python-requests module introduced a VendorAlias import machinery in
v2.5.2 and caused the sys.modules to break. This issue was later fixed in
v2.6.1 of python-requests (see [here](https://pypi.python.org/pypi/requests)).
The solution is to use this version of python-requests, which fixed the
issue.
**Testing Done**
On CentOS 6 full dev
- Validated python-requests v2.6.1 is installed
- Checked for the Metron Indexing service state to be up.
- Checked ambari-agent.log and the error was not seen.
On Ubuntu 14 full dev
- Repeated the same steps as on CentOS 6
**Verification Steps**
- Spin up full dev.
- Verify Metron Indexing service is shown as up and running.
