NSX: log request body to NSX as debug
NSX: log request body to NSX as debug

Previously we never logged the request body that we sent to NSX. This makes
things hard to debug when issues arise as we don't actually log the body of
the request that we made. This patch adds the body to our issue request log
statement.
