Add PKI and Config

[krisnova]

Right now the main repository has a make target that is used to kickstart a local auraed environment.

https://github.com/aurae-runtime/aurae/blob/main/docs/certs.md#generating-client-certificate-material

make pki config

which creates mTLS certs, signs them, and configures a configuration file locally on the filesystem.

Can we please design and introduce the subcommands, flags, and features needed such that we can easily create, sign, manage, and mutate TLS certificates and config files for Aurae directly from the ae tool?

Some examples of what I am thinking:

ae create <domain> # Creates CA
ae create <domain> --user=nova # Create a Nova user
ae sign <domain> --user=nova --root=ca.crt
ae config /path/to/pki/ ~/.aurae/config.toml

Im going to add some tests to the ae pki create command this weekend.

Additionally I would like to proceed with the issue and move additional functionality from make pki config to ae.

Expect PRs. 🤖

Just to create an overview:

• Create Root CA Feat/add pki create #28
• Create CertificateRequest add certificate request for user #53
• Use RootCA and CertificateRequest to create new ClientCertificate Add command to create client certificate #64

After those PRs are implemented, we are compatible with make pki config and could replace it.
