feat: create new telemetry handle that supports connection strings

[BeegiiK]

Reason for Change:

Currently, the telemetry handle can only work with instrumentation keys. If we want to use application insights in sovereign clouds, this would simply fail as the logging is shipped to a default ingestion endpoint and the isPublicEnvironment check.

This PR introduces a new telemetry handle method that takes in a connection string, parses it, updates the configuration appropriately and initializes the new handle

Tested manually by updating DNC to use the new telemetry handle and verified that the logs were shipped to Kusto, with the connection string of the test application insights resource

Due to the original ApplicationInsights-Go repo not being maintained, essential changes to support connection strings could not be merged. Therefore, the source code along with the additional changes were brought over as a separate module

Issue Fixed:

#3730

Requirements:

• uses conventional commit messages
• includes documentation
• adds unit tests
• relevant PR labels added

@BeegiiK I'm not interested in maintaining a soft AppInsights fork. Have you talked to the owner of the repo to see if they would take this contribution?
