Move Semantic Kernel functional tests to default

[cecheta]

Motivation

Currently, the functional tests for Semantic Kernel spawn a separate instance of the application with the environment variable ORCHESTRATION_STRATEGY set to semantic_kernel. However, following #873 , it is now possible to mock the config retrieved from Azure Storage instead of relying on the default config, therefore the semantic kernel tests can be moved to the default suite of tests, with the config file retrieved from Azure storage to have .orchestrator.strategy set to semantic_kernel.

Requirements

A list of requirements to consider this feature delivered

• Move all tests functional tests from sk_orchestrator to default
• For these tests, mock the call to retrieve the file from Azure Storage with .orchestrator.strategy set to semantic_kernel.
