PKI Server CA Certificate Request from cert not work

[fmarco76]

Trying to get a certificate request from a certificate does not work. The error is:

[root@pki /]# pki-server ca-cert-request-find --cert-file ca3_s.pem

TypeError: a bytes-like object is required, not 'str'

A simple conversion of the certificate from binary to string in base/server/python/pki/server/cli/ca.py:642 solve the issue but the request is not found.
