kube upgrade via Horizon - Change popup message from "force" parameter

[Agustin Carranza]

Brief Description
-----------------

"Force" parameter should include offline subclouds when selected to the strategy as the help message says.

After selecting the "force" parameter we dont have the offline subcloud added to the strategy. do we expect to have the subcloud added to the strategy or we have a wrong help message?

if the help message is wrong, I saw force parameter can do:

force kube upgrade to a subcloud which is in-sync with system controller
then we need to change the message based on this functionality.

Severity
-----------------

<Minor: System/Feature is usable with minor issue>

Steps to Reproduce
-----------------

deploy a dc system with multiple subclouds
ensure you have an offline subcloud
select the force parameter and create a strategy to kube-upgrade

Expected Behavior
-----------------

??

Actual Behavior
-----------------

When "force" parameter was selected the offline subcloud was not added to strategy steps:

Reproducibility

State if the issue is 100% reproducible

    Fix for 'Apply to' and 'Force' fields behavior

    On 'Create Strategy' form the following fields are not usable when
    selecting a subcloud:
    * subcloud apply type
    * maximum parallel subclouds
    Now they are hidden in such case.

    Input element for subcloud name was changed to a dropdown list.
    If 'All subclouds' is selected, the strategy is applied to all
    subclouds and the fields mentioned are hidden. If any other
    subloud name is selected, such fields are shown.

    It was created another 'force' element for kubernetes strategy
    which shows a help message that is consistent with the expected
    behavior. The original element is left for 'upgrade' strategy only.

    Test Plan
    PASS:
    Build package
    Install package on DC with at least one subcloud
    Open gui on a browser and navigate to Distributed Cloud Admin ->
    Orchestration -> Orchestration Stragegy -> Create Strategy:
    * Check 'force' parameter is hidden for 'Patch' and 'Firmware' strategy
      types.
    * Check 'force' help text describes actual behavior.
    * Check 'subcloud' field is a dropdown menu and shows available
      subclouds.
    * Check 'subcloud apply type' and 'maximum parallel subclouds' fields
      are not shown when a single subcloud is selected in the dropdown
      menu.
