[FEATURE] Index patterns should have titles?

[kavilla]

Should index patterns have titles themselves? Underneath the hood, index-patterns utilize the title to be the index pattern but should we have a unique title?

In general, the purpose/customer benefit of the saved object title property is that it allows users to create a human-meaningful reference to that object. For simple index patterns, the pattern itself may be a good default title, if the underlying indices also have semantically meaningful names. But for more complicated patterns or distinguishing between two very similar patterns, a separate title property might be useful.

@AMoo-Miki I'm afraid it's as you feared. Here's where we actually set the pattern into the title property on save: https://github.com/opensearch-project/OpenSearch-Dashboards/blob/main/src/plugins/index_pattern_management/public/components/create_index_pattern_wizard/create_index_pattern_wizard.tsx#L200

What's worse, there is not pattern property - the pattern just is the title as far as the SavedObject is concerned: https://github.com/opensearch-project/OpenSearch-Dashboards/blob/main/src/plugins/data/server/saved_objects/index_patterns.ts#L62-L63
