Weird error message installing a not yet valid certificate

[Thiago Paiva Brito]

Brief Description
-----------------
Running a restore on a VM, the playbook failed with a cryptic error message trying to reinstall the certificates from the backup. Retrying to install the certificates directly on the CLI rendered the same error message:

[sysadmin@controller-0 ~(keystone_admin)]$ system certificate-install -m ssl_ca /tmp/ca-cert.pem
Certificate /tmp/ca-cert.pem not installed: Expecting value: line 1 column 1 (char 0)

After I perceived that the VM date was behind the certificate start_date, but the error message needs improvement.

Severity
--------
Minor: System/Feature is usable with minor issue

Steps to Reproduce
------------------
-Create a certificate
-Take a backup
-Revert VM
-Restore backup

Alternatively, just generate the certificate and set the system date to something before the start_date before issuing certificate-install

Expected Behavior
------------------
certificate-install fails with a meaningful message

Actual Behavior
----------------
Message is just "Certificate /tmp/ca-cert.pem not installed: Expecting value: line 1 column 1 (char 0)"

Reproducibility
---------------
4/4
