maxSpareThreads should be removed from the connector configuration of tomcat

In the server.xml file, we have a settings for maxSpareThreads which is currently set to 75. According to the tomcat 5.5 docs, the value is defined as thus:

The maximum number of unused request processing threads that will be allowed to exist until the thread pool starts stopping the unnecessary threads. The default value is 50.

Now starting from tomcat 6, the parameter is being deprecated and such leaving it will just throw warnings in the logs:

Jun 03, 2014 5:18:10 PM org.apache.catalina.startup.SetAllPropertiesRule begin
WARNING: [SetAllPropertiesRule]{Server/Service/Connector} Setting property 'maxSpareThreads' to '75' did not find a matching property.
Jun 03, 2014 5:18:11 PM org.apache.catalina.core.StandardContext setPath

Since Bamboo is now bundled with tomcat 7, this can safely be removed.
