Add index tags (#169)

## Problem

Add support for Index tags.

## Solution

Index tags can be passed as a Map<String, String> to the following
operations:
1. create serverless index
2. create pod Index
3. configure serverless index
4. configure pod index

When configuring tags, following are the special cases:
1. If an empty map is passed as an input, the tags will remain unchanged
2. If an empty value is passed as an input, the tag will be removed

## Type of Change

- [ ] Bug fix (non-breaking change which fixes an issue)
- [X] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to not work as expected)
- [ ] This change requires a documentation update
- [ ] Infrastructure change (CI configs, etc)
- [ ] Non-code change (docs, etc)
- [ ] None of the above: (explain here)

## Test Plan

Updated integration tests for all 4 operations.
