Description of problem:
IPA WebUI should display some warning message when ipa-server upgrade is in
progress in the background so as to make it more robust for end-user.
Version-Release number of selected component (if applicable):
ipa-server-4.5.0-21.el7.x86_64
Steps to Reproduce:
1. Setup IPA server at RHEL 7.3z
2. Setup repo for latest RHEL version ( in my case RHEL 7.4-0day)
3. Initiate upgrade on the server "yum -y update 'ipa*' sssd
4. While the upgrade is in progress, access the UI
Actual results:
1. After step4, the UI may or maynot be accessible depending on what packages
are getting updated in the background.
Expected results:
There should be some warning message at the UI, for the user to suggest that
there is an upgrade process running in background and he/she can try accessing
after sometime.
Additional info:
Similar warning message can be setup for Replica server.
