Allow index aliases be independently optional
Stemming from the conversation here: https://discourse.hibernate.org/t/elasticsearch-index-alias-opt-out/4724/2
Allow for index alias usage to be optional. Not in all circumstances are the use of write and read aliases necessary.
Allow the write and read aliases to be independently optional. If write alias is not provided, default to the index name itself. Same for the read alias.
I had already created a ticket here: HSEARCH-4102. Sorry, I forgot to mention it on the discussion.
Closing as duplicate.
Thanks for the feedback!
