Undeploy operation wording is not unified

There is an effort to unify wording of HAL deployment operations wording with CLI deployment command wording. Actually, the HAL Remove deployment operation is not unified with CLI deployment undeploy command.

In domain mode, there are two actions:

1) remove the deployment from a server-group, but the deployment remains in the content repository.

• This action is named "Undeploy" in the content repository preview , no change here.
• This action is named "Remove" in the server-group, so we need to change it to "Undeploy"

2) remove the deployment from the content repository. In this case the word "Remove" sound more appropriate to the removal of content from the content repository, so do not need a change.

In standalone mode, the word is "Remove", so a change to "Undeploy" to align the wording.
