[#122] Enable load balancing strategy property configuration

smcvb commented 11 months ago

This pull request introduces logic to the MultiTenantEventProcessorsControlService that checks whether the user has set load-balancing strategy properties in their properties file. This logic, although present in the EventProcessorsControlService it inherits from, needs a rewrite because the multi-tenant variety needs to deal with the fact the processor name and context are concatenated.

Thus, a part of the changes is the mapping from processor name to strategy. The other, larger part, is the actual invocation of the AdminChannel to set the load balancing strategy and to enable automatic load balancing (if enabled). This latter part closely resembles the implementation of the EventProcessorsControlService on this subject, by the way.

In doing the above, this pull request resolves #122.
