Review request for Ambari and Andrii Tkach.


Bugs: ambari-8350
    https://issues.apache.org/jira/browse/ambari-8350


Repository: ambari


Description
-------

When there are more than 25 hosts in the cluster, the host selection pulldown turns into a
type-ahead text field.
This is a common widget that is used for various pages like Installer > Assign Masters,
Move > Select Target Host, etc.
The problem is that if you copy paste the hostname directly, the UI shows RED .  The user
has to know to click or hit enter on the suggested hostname (which is the same as the user
pasted in but with RAM and # cores.  Also, when the user makes this selection, the text field
shows RAM & # cores.  

1. It should just work if the user copy pastes a valid hostname
2. Once a selection is made from type ahead, the text field value should NOT include RAM &
# cores.
