fixes #6607 / BZ 1106565 - Content View Package Filter Rules - allow duplicate name

Prior to this commit, a user could not create multiple package filter
rules for the same package (i.e. name) but different specific versions.

For example, if a repo had the following packages:
  package-0:1.0.0
  package-0:2.0.0
  package-0:3.0.0
  package-0:4.0.0

A user could not create rules to include/exclude the following packages:
  package-0:2.0.0
  package-0:4.0.0
fixes #6619 / BZ 1111733 - Lifecycle Environment: do not update label

The lifecycle environment label was being 'auto updated' when a user
would change the environment name.  This should not be done as the
label is intended to be read-only.
fixes #6624 / BZ 1105617 - content host package actions - disable buttons when busy

This commit contains a minor change to disable the ability to initiate a new action,
until the current action has been accepted (202) by the server.  The most common
use case for this is if the user were to double-click the 'Perform', 'Update All'
or '(X)' items in the UI.

Without this change, the user might observe an error like the following in the log:
  ForemanTasks::Lock::LockConflict: Required lock is already taken by other running tasks.

In spite of the above error, the user could later go back and re-execute a new request.
