SUMO-245309 Add the terraform support for Azure metric sources

[yuting-liu]

In this PR, we added the terraform support for Azure metrics sources.

Changes

• Azure metrics sources are Polling sources, so the major changes are added in resource_sumologic_generic_polling_source.go for changes specific to azure metrics sources

1. Added new authentication type used by Azure metrics sources. Eg:

authentication {
  type = "AzureClientSecretAuthentication"
  tenant_id = "<azure_tenant_id>"
  client_id = "<azure_client_id>"
  client_secret = "<azure_client_id>"
}

2. Added new path type used by Azure metric sources.

path {
	type = "AzureMetricsPath"
	environment = "Azure"
	limit_to_namespaces = ["Microsoft.ClassicStorage/storageAccounts"]
	azure_tag_filters {
		type = "AzureTagFilters"
		namespace = "Microsoft.ClassicStorage/storageAccounts"
		tags {
			name = "test-name-1"
			values = ["value1", "value2"]
		}
	}
}

One thing to mention here for TagFilters field in Azure metrics sources, we added a new azure_tag_filters instead of using the same tag_filters as CloudWatch sources and kinesis metrics sources. The major reason is that for tags, the schemas are different and it requires to have a detailed schema definition in terraform world, which is why we added this new field. And for azure_tag_filters, we required type = "AzureTagFilters" to be required.

Test

• Added the unit test for azure metrics source
• Run the test locally

--- PASS: TestAccSumologicAzureMetricsSource_create (4.36s)
PASS
ok  	github.com/SumoLogic/terraform-provider-sumologic/sumologic	4.891s

--- PASS: TestAccSumologicAzureMetricsSource_update (5.58s)
PASS
ok  	github.com/SumoLogic/terraform-provider-sumologic/sumologic	6.100s

• However Tests / Matrix Test (1.0.3) (pull_request) are not passing with the following error:

  
  Error: ***
    "status" : 400,
    "id" : "57TBO-MK628-NNH3R",
    "code" : "collectors.validation.fields.invalid",
    "message" : "Permission denied for Azure API: 'reason=Self-suppression not permitted'."
  ***

The reason is that we need to ask the terraform team to help us to configure the following secrets for the test to run:

        SUMOLOGIC_TEST_AZURE_TENANT_ID:  ${{ secrets.SUMOLOGIC_TEST_AZURE_TENANT_ID }}
        SUMOLOGIC_TEST_AZURE_CLIENT_ID:  ${{ secrets.SUMOLOGIC_TEST_AZURE_CLIENT_ID }}
        SUMOLOGIC_TEST_AZURE_CLIENT_SECRET:  ${{ secrets.SUMOLOGIC_TEST_AZURE_CLIENT_SECRET }}

I'll work with the team on fixing it: slack: #terraform-team

@ErikAtSumo The current the unit test failure is about the azure event hub sources, which irrelevant with the changes in this PR. Can you please help to try to merge this PR?

Hi @yuting-liu , I'll have a look now.

@yuting-liu Indeed, these tests are also failing on master for the same reason. I'll merge this PR and figure it out separately.
