Bug 1731185

Description of problem:
When restoring from NFS using the appliance console option 6 and the evmserverd is running, I can see the error in evm.log:


----] I, [2019-07-18T10:30:19.327877 #29323:11b8f54]  INFO -- : MIQ(MiqNfsSession-mount_share) Connecting to host: [10.8.198.142], share: [/srv/export/db_backup/tmp] using mount point: [/tmp/miq_20190718-29323-v3bw4v]...

I can see no indication that something had failed in the appliance console:

Restore Database From Backup


Note: A database restore cannot be undone.  The restore will use the file: nfs://10.8.198.142/srv/export/db_backup/tmp/evm_db.backup.
Are you sure you would like to restore the database? (Y/N): y

Restoring the database...
*** Hangs forever here***


I also would expect the log lines about restore in the appliance_console log rather in the evm.log


Version-Release number of selected component (if applicable):
5.10.7.1

How reproducible:
2/2

Steps to Reproduce:
1. Backup the db to nfs using option 4
2. Try restoring the db from nfs using option 6 without shutting down the evmserverd.
3.

Actual results:
No progress informatin about the restore. No error.

Expected results:
 * restore operation either shuts down evmserverd and then restores or
 * error message about that user needs to shut the evmserverd down appears in the apliance_console stderror/stdoutput

Some progress information would be great to have.
