New Metrics V2 resource which uses V2 endpoints

[sukhhanda1]

Why this change?
Fixes issue: #713

The current metrics search resource is not compatible with V2 metrics searches. The UI has completely migrated to V2 metrics searches and resources created with v1 APIs are not compatible.
In order to fix this, we have provided support for metrics_searches_v2 which uses V2 endpoints for metrics searches resource creation.

API for reference:
https://help.sumologic.com/docs/api/metrics-searches-v2/

Testing performed:
The test cases sumologic/resource_sumologic_metrics_search_v2_test.go are run with one of the sumologic enviroments and I was able to verify the newly created resource is visible in the personal folder in the library. On opening the resource, all the details are correctly set.

@sjain05 It is working fine when I am running the tests on my local. Do we know which enviroment do we use to run tests on PR builder? I would like to see what this error code says SSKT8-FDO0Y-E83H8.

[sukhhanda1]

@sjain05 Might have been some intermittent issue. Passed on Retry.

lgtm, but please address the comments

couple of things -

1. you need to add the resource reference here https://github.com/SumoLogic/terraform-provider-sumologic/blob/master/sumologic/provider.go#L45
2. you need to add documentation here https://github.com/SumoLogic/terraform-provider-sumologic/tree/master/website/docs/r for this new resource

1. The reference is already added here.
2. I have added the docs with a message about deprecation of metrics_search resource.
