Michael Johnson 12b1e57561 Fix sysctl settings for amphora image
This patch fixes two things:
1. The sysctl settings were failing because some conntrack modules
were not loaded anymore.
2. I fixed the sysctl-set-value scripts to be able to handle
multi-value settings, such as tcp_rmem, in tripleo-image-elements[1].
Here I have removed the workaround we had in Octavia.
