How do I migrate from the old tls feature when using self-signed certificates?

[orzen]

I already had something working with the old tls feature flag but I tried to upgrade to tonic 1.14.1 and the tls feature flag was replaced with a number of options for different crypto providers.

1. How do I migrate from the old tls feature flag?
2. Why do I need a crypto provider when I use a self-signed CA?

Seems like I solved it with the help from Conrad on Discord.

Solution:

1. Add rustls.
2. Make sure that the feature flags aws-lc-rs and ring are disabled on rustls.
