UTF-8 characters in repo description break check script

[laugmanuel]

If there is a repo containing UTF-8 characters in it's description, the script fails with the following error:

Traceback (most recent call last):
  File "./check_katello_sync.py", line 370, in <module>
    main(options)
  File "./check_katello_sync.py", line 355, in main
    check_products()
  File "./check_katello_sync.py", line 158, in check_products
    check_product(product)
  File "./check_katello_sync.py", line 106, in check_product
    product["label"], product["description"], product["last_sync"][0:19]
UnicodeEncodeError: 'ascii' codec can't encode character u'\u2019' in position 322: ordinal not in range(128)

This is caused by:

check_katello_sync/check_katello_sync.py

Lines 102 to 103 in 1c1e870

	LOGGER.debug("Product '{0}' ({1}) was synced at {2}".format(
	product["label"], product["description"], product["last_sync"][0:19]

If this line is changed to the following, the script works again:

        LOGGER.debug("Product '{0}' ({1}) was synced at {2}".format(
            product["label"], (product["description"] or '').encode('utf8'), product["last_sync"][0:19]
