Fixed crash when record has hardware but not ends fields

[colinjc]

When parsing our dhcpd.leases file the library was crashing on a record because it has the hardware field but not he ends field, so it tries to construct and fails with a KeyError here

        if properties['ends'] == 'never':

lease 172.23.251.150 {
starts 4 2015/09/10 00:29:00;
tstp 4 2015/09/10 00:28:44;
tsfp 4 2015/09/10 00:29:00;
atsfp 4 2015/09/10 00:29:00;
binding state free;
hardware ethernet 00:21:cc:06:94:e9;
uid "\001\000!\314\006\224\351";
}

LGTM.

Out of curiousity how did you produce that lease? Static lease?

[andir]

One more thing: Do you mind adding that kind of case to the tests?

[colinjc]

@andir Honestly, I'm not sure how the lease was produced since I had nothing to do with the configuration of the server. I assume that you're right and it is a static lease though judging from the age.

I can quickly add a test, but I'm not sure where to add them. Should I add a record to the debian7 file and put the test in test_iscDhcpLeases.py?

[MartijnBraam]

Thanks for the contribution.

The test code should go in test_iscDhcpLeases.py and the record should go in a seperate file in the test_files directory (the same as the unittest for the options)
