[BUG] Reporting indicies are configured with no replicas

[akbhatta]

Describe the bug
in report-definitions-settings.yml and report-instances-settings.yml, number_of_replicas set to 0 with auto_expand_replicas: "0-1". In certain circumstances if master node goes out of network, there is a possibility that there are no replica nodes to replace it.

May be we can set to at least 1 replica available always?
