Enabling/disabling sending anonymous statistics in UI

[Alexander Kislitsky]

Option for enabling/disabling sending anonymous statistics should be provided in the Nailgun UI.
Option is for whole Fuel installation.

Also we should show list of sending anonymous info:

* Operation type (adding cluster, adding node, deployment,
  removing node, e.t.c.)
* Operation start and finish time (in UTC)
* Distribution / OS
* Reference architecture (e.g. HA)
* Network type (Nova-Network, Neutron with VLAN, GRE, NSX, etc.)
* Hypervisor (KVM, QEMU, vCenter, etc.)
* Storage options (Glance w/ Ceph, Glance w/ Swift, Cinder w/ LVM,
  Cinder w/iSCSI, Ceph, etc.)
* Related Projects (Sahara, Murano, Ceilometer, etc.)
* Number of nodes deployed
* Roles deployed to each node
* Number of environments
* Installation anonymous identifier (generated once during installation)
* Fuel version info (build number, release, build id, nailgun sha,
  fuelmain sha, ostf sha, e.t.c.)
* OpenStack version info
* Settings modified on Settings tab
* Interfaces configuration
* Disk layout
* Hardware (so we can differentiate between virtualbox and bare metal installs)
* Network verification - whether it was used, and what was the result
* Networking configuration
* Actual time (in seconds) that is took to complete the operation
* Is there any manual customizations of nodes metadata done
* Kernel parameters
* Admin network parameters
* PXE parameters
* DNS parameters
* Is fuel menu used
* Is OSTF used, and tests results

On some operations we can provide only part of statistic info. All the identifying
information (passwords, ips, names) is sanitized.
