Issue:
[Beta] Cannot set Cloud Role Name and Instance values
## Description
Although I set cloud role name, instance id and namespace as described in the latest docs, I still see the default values (role='Web', instance=hostname) in the Application insights .

## Importance
1. We have been using this SDK for CLI tool which runs on local machines, we do not want to collect/report hostname for privacy reasons.
2. Default Role (Web) doesn't not reflect our tool's role. However, this is less important comparing to above item 
 
## Code
```js
const { ApplicationInsightsClient, ApplicationInsightsConfig } = require("applicationinsights");
const { SemanticResourceAttributes } = require("@opentelemetry/semantic-conventions");

const config = new ApplicationInsightsConfig();
config.connectionString = '<MyConnectionString>';

const appInsights = new ApplicationInsightsClient(config);

const traceResource = appInsights.getTraceResource();
const metricResource = appInsights.getMetricResource();
const logResource = appInsights.getLogResource();

// ----------------------------------------
// Setting role name and role instance
// ----------------------------------------
traceResource.attributes[SemanticResourceAttributes.SERVICE_NAME] = "my-helloworld-service";
traceResource.attributes[SemanticResourceAttributes.SERVICE_NAMESPACE] = "my-namespace";
traceResource.attributes[SemanticResourceAttributes.SERVICE_INSTANCE_ID] = "my-instance";

metricResource.attributes[SemanticResourceAttributes.SERVICE_NAME] = "my-helloworld-service";
metricResource.attributes[SemanticResourceAttributes.SERVICE_NAMESPACE] = "my-namespace";
metricResource.attributes[SemanticResourceAttributes.SERVICE_INSTANCE_ID] = "my-instance";

logResource.attributes[SemanticResourceAttributes.SERVICE_NAME] = "my-helloworld-service";
logResource.attributes[SemanticResourceAttributes.SERVICE_NAMESPACE] = "my-namespace";
logResource.attributes[SemanticResourceAttributes.SERVICE_INSTANCE_ID] = "my-instance";

appInsights.start();

const tracer = appInsights.getTraceHandler().getTracer();

const span = tracer.startSpan("my-span");
span.addEvent('my-event', { myEventAttribute: 'my-event-attribute-value' });
span.end();

appInsights.flush().finally(()=>{
    console.log("Done");
});
```

## Application Insights results:

## Expected Results: 
- cloud_RoleName => my-helloworld-service
- cloud_RoleInstance => my-instance 



Pull request description:
[Beta] Allow custom OTel Resource to be passed in configuration
Fixes #1089
Related to #1083 

Breaking change, Resource reference is not kept in OpenTelemetry side, a copy is created that is immutable, we should expose Resource as configuration option that can be set before the SDK is initialized,  allowing customer to cloud role name and instance properties and any other custom one. I will update documentation in release PR
