Description of problem
======================

Set of EC pool profiles is hardcoded and doesn't contain all supported EC
configurations.

Version-Release
===============

On RHSC 2.0 server machine:

rhscon-core-selinux-0.0.41-1.el7scon.noarch
rhscon-core-0.0.41-1.el7scon.x86_64
rhscon-ceph-0.0.40-1.el7scon.x86_64
rhscon-ui-0.0.53-1.el7scon.noarch
ceph-installer-1.0.15-1.el7scon.noarch
ceph-ansible-1.0.5-32.el7scon.noarch

On Ceph 2.0 storage machines:

rhscon-core-selinux-0.0.41-1.el7scon.noarch
rhscon-agent-0.0.18-1.el7scon.noarch

How reproducible
================

100 %

Steps to Reproduce
==================

1. Install RHSC 2.0 following the documentation.

2. Accept few nodes for the ceph cluster.

3. Create new ceph cluster named 'alpha', 

4. Go to Storage -> Pools and click on "Add Storage" button, then select
   Object storage option to reach "Add Object Storage" form.

5. On the "Add Object Storage" page, set type to "Erasure Coded" and then
   try to configure EC profile.

Actual results
==============

Console provides predefined set of configurations for "EC Profile":

 * 2+1
 * 4+2
 * 6+3
 * 8+4 

It's not possible to select a different configuration.

Expected results
================

EC Profile is configurable by a separate option for both n and k (asking for
actual number for both), so that all valid and supported EC profile
configuration could be selected.
