Switch to env var provisioners for ngrok

[AndyTitu]

Platform or tool

Ngrok

Desired or expected behavior

Authtoken and api key can be provisioned via the newly exposed env vars NGROK_AUTH_TOKEN and NGROK_API_KEY.

We need to realise that NGROK_API_KEY was recently introduced so maybe not all ngrok users will benefit from this yet. We should consider defining a versionChecker inside our plugins that would only allow the plugin to be run if the user's ngrok version is above a certain threshold.

Current behavior

Ngrok provisions secrets using the config file. This is not as straightforward as provisioning via env vars because it involves handling already existing non-sensitive config files. It requires logic for looking at default locations as well looking at --config flag. The case when multiple config flags are specified is not supported because the merging behaviour does not fit with our FIFO file provisioning.
