Hans Lindgren c126d36640 Make scheduler filters/weighers only load once 
Right now, filters/weighers are instantiated on every invocation of the
scheduler. This is both time consuming and unnecessary. In cases where
a filter/weigher tries to be smart and store/cache something in between
invocations this actually prohibits that.

This change make base filter/weigher functions take objects instead of
classes and then let schedulers create objects only once and then reuse
them.

This fixes a known bug in trusted_filter that tries to cache things.

Related to blueprint scheduler-optimization
