Typecheck variables in config files

[teunis90]

Today we got a failed backup due to a config file typo:

Reading main config from /etc/autorsyncbackup/main.yaml
Writing to logfile /var/log/autorsyncbackup/autorsyncbackup.log
Starting AutoRsyncBackup
Traceback (most recent call last):
 File "/usr/local/bin/autorsyncbackup", line 48, in <module>
   director.processBackupStatus(job)
 File "/usr/local/share/autorsyncbackup/src/director.py", line 236, in processBackupStatus
   job.backupstatus['fileset'] = ':'.join(job.fileset)
TypeError: sequence item 0: expected string, int found

We should not only check the YAML file for vadility but also type check the individual variables.

Anybody a good idea how to accomplish this?
