Constructs a new ContextSelectorAdmin. 
Params:
contextName – name of the LoggerContext under which to register this
           ContextSelectorAdmin. Note that the ContextSelector may be
           registered multiple times, once for each LoggerContext. In web
           containers, each web application has its own LoggerContext and
           by associating the ContextSelector with the LoggerContext, all
           associated MBeans can be unloaded when the web application is
           undeployed.
