What does this PR do and why?

Describe in detail what your merge request does and why.

In preparation for searching samples via complex metadata criteria, this PR adds in Searchkick as a dependency which uses OpenSearch (An open source ElasticSearch alternative) to index our Samples including metadata which allows complex querying. This PR just updates the Sample model to include indexing and updates the existing Project and Group Samples table to use SearchKick to perform the existing searches.
