Description

Disable ElasticIndexProviderService when a system property is passed and make sure elastic indexes return infinity cost in that case.
E.g:

 -Doak.elastic.disabled=true

Additionally, a unit test should be written to test query execution when both ES & lucene indexes are present and ElasticIndexProviderService is disabled and elastic indexes return infinity cost.
