 Title: #2308: Delete empty keytab during client installation
Action: opened

PR body:
"""
Client installation fails if '/etc/krb5.keytab' exists as a zero-length file. Deleting empty keytab before proceeding with the installation fixes the problem.

Signed-off-by: Armando Neto

**Note to reviewers:**
Function implemented instead of an in-place solution, so it could be easily tested, if this solution is overkill I don't mind to remove the test case and move the check-and-delete procedure to where the function is being called.
