Patched Service Doesn't Display Correct Hadoop Version on Stacks Page

STR:

• Install ZK, YARN, HDFS with HDP 2.5.0.0
• Apply a PATCH VDF for ZooKeeper for 2.5.4.0

Notice that on the stacks/versions page, the columns show ZooKeeper as green for both versions.

Also - notice that when clicking on the hosts number to see where a particular repository is installed, the text that is displayed sounds a little off. It says

"HDP-2.5.4.0-121 Version is Current on 3 hosts"

We can probably just drop the word "version". And maybe change the word "Current" to applied. Something like this:

"HDP-2.5.4.0-121 is applied to 3 hosts"
