securityonion-elastic: dashboard updates

[dougburks]

• Remove HTTP - Summary viz from HTTP dashboard as it is slow and can cause issues
• Remove the Total Bytes By Source Port viz from the Connections dashboard; replace with map links from above to place the map links closer to the Service by Destination Country viz
• Add a Total Bytes by Source and Destination IP pair viz to Connections dashboard
• Indicator dashboard should include a top 50 source IP viz and top 50 dest IP viz
• Add viz for DNS response codes (rcode_name)
• Bro Notice "Logs" saved search should include note rather than message
• Create a viz for total logs of each type per sensor and device
• Consider using "syslog-host_from" rather than "host" in OSSEC-related viz
