feat: adding Elastic as a metric provider

[SandeepD2697]

fixes #3727

Hey @mowies I have taken the code changes from the previous contributors and updated it accordingly by adding it in the provider.go and calling when it is elastic. This is my initial version please have a look and let me know the changes I need to make or any enhancements.

For now the methods purpose are-

GetElasticClient: Creates a new Elasticsearch client.
FetchAnalysisValue: Runs a query to get analysis results and returns the metric value.
EvaluateQuery: Runs a metric query for the last 30 minutes and returns the metric value.
runElasticQuery: Executes a query on Elasticsearch and returns the result.
extractMetric: Gets the metric value from the Elasticsearch result.
