Ironic OSTF tests can not access endpoint

[Kyrylo Romanenko]

1. Deployed cluster with the following configuration:
1 Controller + Ironic
1 Compute + Cinder
1 Base OS

Settings:
Compute - QEMU
Network - Neutron with VLAN segmentation
Storage Backends - Cinder LVM over iSCSI for volumes

2. Open OSTF tab and run Ironic-related tests:

- Check that Ironic can operate nodes - FAIL on first step:
Create Ironic node with fake driver.

- List Ironic entities
List chassis. - FAIL on first step:

Both tests failed with error:
ConnectionRefused: Error communicating with http://192.168.0.2:6385 [Errno 101] Network is unreachable

 http://192.168.0.2:6385 is endpoint for Ironic.

But I can successfully create ironic node and list nodes, chassis etc via CLI ironi client from controller node.

Use requests lib in HTTPClient

This change proposes switch to requests lib instead using
HTTPConnection and VerifiedHTTPSConnection, requests lib is
recommended for higher-level http client interface.

Also HTTPConnection can't work with API server behind proxy.
