Move action-and-meta-data to (indexing) type definition

[danielmitterdorfer]

Today, the action-and-meta-data property, which describes how to treat a source file w.r.t. to that line for bulk indexing, has to be set on the bulk-index operation. However, it is actually a property of the source file itself. Hence, we should move this property to the source file definition.

This change will break existing tracks if a user has defined this property on the bulk-index operation. As this is not a very common use case and the migration is rather simple, we go down that route.

Steps to migrate

In case you get the following error when running a benchmark you need to migrate your track:

The parameter "action-and-meta-data" is not supported anymore. 
Please specify instead the boolean flag "includes-action-and-meta-data" 
on each type definition.

1. Remove the property action-and-meta-data from the affected indexing operation.
2. You need to add the property includes-action-and-meta-data on all types that you've defined. The value depends on the previous value of action-and-meta-data:
   2.1 If action-and-meta-data was sourcefile, set includes-action-and-meta-data to true.
   2.2 If action-and-meta-data was generate, set includes-action-and-meta-data to false.
   2.3 The mode action-and-meta-data = none is not supported anymore. If you have used it before and still need it, please raise an issue and explain your use case. The suggested migration approach is to set includes-action-and-meta-data to false and let Rally generate the action and meta-data line.
