Add Microsoft Application Insights as a supported trace datastore

[kdhamric]

We want to add Microsoft Application Insights as a supported trace datastore so Azure customers using tracing can utilize Tracetest and trace-based testing techniques against their distributed apps. We have confirmed with the team at Microsoft that the trace data can be queried via the Azure Monitor Log Analytics API (https://learn.microsoft.com/en-us/azure/azure-monitor/logs/api/overview).

AC1: Microsoft Application Insights is added to the Settings screen under Configure Data Store

AC2: Once configured, Tracetest is able to use the API to successfully pull back a trace from Azure Monitor and build tests based on it.

AC3: Microsoft Application Insights is added as a supported trace data store in the docs under https://docs.tracetest.io/configuration/overview.

AC4: There is a recipe showing how to use Microsoft Application Insights with an Azure based project and test the project via Tracetest.

AC5: This integration is added to the Tracetest.io integration page.
