Subject: [PATCH] tests: improve coverage

Add error condition checks.  Add lease file binding states.  Check all
output formats.  Check leases file that is in mad order, cse all sorting
methods when checking this.  Use json output to check status classfications.
Add cidr range checks.  Add conf include and comment parsing input checks.
