[UI] does not display a custom message if 'action:none' option used

[Artem Savinov]

Detailed bug description:
In the environment_config.yml written restrictions with defined parameters 'action: none' and 'message'. Example:
    restrictions:
      - condition: 'settings:nsxv.nsxv_metadata_nova_client_priv_key.value.name != null and settings:nsxv.nsxv_metadata_nova_client_cert.value.name == null'
        action: 'none'
        strict: false
        message: 'If "Private key" loaded, also need load "Client certificate for nova metadata api server"'
 When restrictions triggered is not displayed custom message, example attached.

Steps to reproduce:
1) Install NSXv plugin in Fuel
2) Load "Client certificate for nova metadata api server" or "Private key" in "Network" tab -> "Network Settings" -> "Other" -> "NSXv plugin"
3) Move the mouse cursor on the yellow triangle

Expected results:
Showing a custom message.
Actual result:
Showing a "standard" message

Description of the environment:
Fuel #203
NSXv plugin used from https://review.openstack.org/#/c/306481/

    Fix layout of file input

    [type=file] input is hidden now by opacity:0 css style.
    But it still overlaps the input label and warning tooltip.
    This commit fixed this by hiding the input with display:none.
