ADR Support self-signed certificates for elasticsearch

Context and Scope

Search Service does not support HTTPS connections with self-signed certificates for elastic search.

Decision

Add a property 'security.https.certificate.trust' into application-*.properties.

If it is 'true', we will use TrustSelfSignedStrategy() in org.opengroup.osdu.search.util.ElasticClientHandler that trusts self-signed certificates.

Rational

We would use self-signed certificates for elastic search instead of signed certificates.

Consequences

These changes could affect all providers due to these things will be implemented in search-core.
