Possibility to switch between http and https protocol

[itsDamon]

There could be some cases where the DevOps website is hosted on HTTP instead of HTTPS.
In the code at line 47 of AzureDevopsClient.ts the url is forced to https.

BaseURL = https://${settings.azureDevopsSettings.instance}/${settings.azureDevopsSettings.collection}/${settings.azureDevopsSettings.project};

It would be nice to be able to choose between the two increasing the accessibility to the plugin for everyone.
