Add additional fields to SO chooser component in VM creation

[elenaustyugova]

This issue is a continuation of #502

Acceptance criteria

1. Characteristics should be separated in "main" (основные) - was done in Change service offering chooser component in VM creation and VM details sidebar (main characteristics) #502 and additional (дополнительные)
2. A table should contain main characteristics of each service offering. Additional characteristics should open only when needed

• Main characteristics:
  -- CPU Cores (Ядра CPU)
  -- CPU (MHz) (CPU (МГц))
  -- Memory (Память (МБ))
  -- Network Rate (Mb/s) (скорость сети)
  - Additional characteristics: all the rest from original CS interface

3. A button "Show additional fields" ("Дополнительные характеристики") should be placed above cancel and save(change)
4. If the button is clicked - additional columns should appear on the right side, user can see it by scrolling
5. Document this feature in Custom features local document

Pay attention to units of measure! (not KB, but MB etc)

Connected feature ID:

• vm_creation_so
• vm_creation_so_custom

Errors:

1. Fields of custom SO parameters allow input any characters in browsers FF (ver. 58.0.1 64bit), MS Edge (ver. 41.16299.15.0) and MS IE (ver. 11.192.16299.0)
   Expected result: These fields allow input only numeric characters.
   

2. SO doesn't change in browser MS IE (ver. 11.192.16299.0) when editing from sidebar VM.

1. IE, MS Edge, and FF do not support input type=number correctly, that is why you do not see arrows and are able to insert characters into fields. But form provides validation, and if you insert characters, the submit button is disabled (see attached video). I suppose that this type of validation and this kind of form behavior are suitable.
2. I so sorry, but I could not reproduce the second point. I attached the video. All operations performed correctly in MS IE.
