Add elasticsearch for omnisearch

[zackarychapple]

In order to make the search interface in the header an omnisearch we need to add a better search engine. Adding Elasticsearch will make omnisearch much easier.

• Add elasticsearch https://www.elastic.co/elasticsearch/
• Create elasticsearch listener on nestjs for system event ingest
• Create docker instance of elasticsearch
• Create elasticsearch seed
• enhance events to populate the search index on CRUD events
• Update search box to use elasticsearch instance
