Update manage script to automate set-up

[esune]

The manage script has updated to automate the steps to start-up vc-authn in various modes:

• the user will be prompted to select whether they want to run in single-tenant or multi-tenant/traction mode
• the user will be prompted to choose whether to use ngrok to expose the services or not

Both curl and jq are being executed in a docker container, removing the dependency for separate binaries on the path.

Ngrok containers have been moved to a separate compose project file: they need to be started before all of the other services in order to retrieve the public URLs and use set environment variables using their values.

I have not been able to test whether this works with traction or not as I cannot start the project in its current state - @Jsyro please let me know if you can run the code and it works.

Resolves #210

[esune]

I am still trying to upgrade the ngrok containers to use the official, more regent image. Other than that the changes should be good to go.

When using the 'multi-tenant' option, I ran into two issues. See comments.

[esune]

It looks like there is an issue with the newer ngrok images, I will wait until that is resolved before I attempt to upgrade again the configuration. See ngrok/docker-ngrok#25

[esune]

Added some tweaks that should make quality of life better when restarting the project while keeping the same settings, and refreshing ngrok endpoints if necessary. If this gets us close enough to where we want to be I'd lean towards merging/closing and logging more specific issues about what needs tweaking as we find out.

Great changes, still some minor exceptions I need for my development environment, but this should work for everyone else.
