Reorder content of tab navigation on Service details page

Currently, the first tab is 'Servers & Sessions', second tab is 'Parameters & Diagnostics'. The current sessions table, current connections graph as well as Router Diagnostics table, their values changes over time. However, only connections graph and sessions table are set to poll data every 10 seconds.
I think we should group those tables into a tab called 'Session & Diagnostics', so now we can observe changes in one place. Then parameters table is moved to a tab called 'Parameters & Relationships', this makes sense since we show parameters, relationships of the service and those tables are editable.
