Task(OpenSearchMigration) Adding the necessary dependencies and a client to interact with the service Refs: #34148

[fabrizzio-dotCMS]

Proposed Changes

• We're adding here the required libraries to connect to OpenSearch 3.0
• We're creating a client to connect to OpenSearch 3.0
• We're creating a ClientProvider that reads the configuration and instantiates a new client accordingly
• We're adding a new configuration so our new OpenSearch client can be tested against an actual running instance
• The actual ES configuration remains the same, while the new one we're introducing is getting named as 'upgrade.'
