1151490 - Repo group publish  fails with NoneType error

https://bugzilla.redhat.com/show_bug.cgi?id=1151490
If optional keys in the config are not specified then by default they are None
(except http/https).Validate_export_config() was not checking whether export_dir
(optional key) is None, and this led to the error when repo group publish was done
via pulp-admin.

1153378 - remove SSLInsecureRenegotation from pulp_rpm.conf

This setting was enabled for older clients but is no longer needed. Clients
updated after 2010 should not need this flag.

Further documentation on this issue is in the BZ.
