There is "Launch Dashboard" link for hosts in Hosts page when cluster is not yet imported

Description

There is "Launch Dashboard" link for hosts in Hosts page when cluster is not yet imported, which is not expected behavior, as verified by @julienlim:

if no cluster is imported,, the grafana dashboard button should not be visible

Version

Latest snapshot build from master branch (if not fixed, it will be part of upcoming 1.5.2 version):

tendrl-ui-1.5.1-20170915T080405.521a085.noarch

Steps to Reproduce

1. Prepare machines with GlusterFS cluster, including gluster volume (I used nightly builds and volume_usmqe_alpha_distrep_4x2.create.conf)
2. Install Tendrl via tendrl-ansible there, using snapshot builds
3. Log into the Tendrl web interface as an admin user
4. Click on "Hosts" item in the menu to get to the Hosts page
5. See hosts listed on the page

Actual Results

There are buttons linking to Grafana dashboard for all machines, even though the cluster hasn't been imported yet.

To provide a complete reference here, the linked dashboard looks like this:

Expected Results

There are no links to Grafana dashboard at this point. The links will be shown only later, when the cluster is imported.

This issue has been discussed during Daily meeting of developers of Tendrl on 2017-09-18: api may need to provide additional information for ui to check if hosts is part of imported cluster, @r0h4n and @gnehapk know the details.

@mbukatov Its fixed in tendrl-ui-1.5.2-20170919T120332.90b043e.noarch.rpm. Please verify.

Verifying with tendrl-ui-1.5.2-20170925T180704.770936f.noarch and it works, Launch Dashboard buttons for hosts of not imported cluster are grey out and it's not possible to click on them
