Pass resourceType instead of resourceIndex to resourceSharingClient

[cwperks]

Description

This PR is related to the changes in opensearch-project/security#5713 to support multiple resource types in the same index. There's a small change in all ResourceSharingClient methods to accept type in the place of index.

resource type <-> resource index is a many-to-one relationship (think dashboards saved objects where multiple saved object types are in the same index).

On another note, ResourceSharingClient is used in instances where a mechanism doesn't currently exist as in parent<->child relationships (like a detector and results where all results are associated with a detector). Security is working on a mechanism to support this natively to obviate the need for ResourceSharingClient and instead abstract all the logic behind-the-scenes to the security plugin.
