View and query logs, metrics, and traces in Application Insights

[polatengin]

As a project developer, I want a set of basic KQL queries that utilize Application Insights tables saved to the repository, so that the team can begin familiarizing with querying Application Insights using KQL

• Documentation added that outlines how to retrieve application logs and metrics
• At least 1 metric's retrieval process documented
• At least 3 KQL queries that use resource-specific Application Insights tables documented (https://learn.microsoft.com/en-us/azure/azure-monitor/app/data-model-complete)
