[Enhancement] Publish role for install opensearch to galaxy

[patsevanton]

Hello! Thanks for opensearch role

Could developers publish role for install opensearch to galaxy ?

[pvanagtmaal]

Are there any plans for this? I'm currently using another (sub-optimal) role for installing OpenSearch because I need to integrate the code into my platform repository

I've added the initial ansible-galaxy metadata in #179 . next required steps would be:

• Someone that can speak for opensearch should request the opensearch namespace.
• We should add automation to publish the collection to galaxy on release
