Extend WithDockerEndpoint method with Docker.DotNet.Credentials parameter

[MarcinSzyszka]

Is your feature request related to a problem? Please describe.
I want to connect to docker with TLS and I want to pass credentials object prepared by my own - exactly the same way as it is done in Docker.DotNet library used in dotnet-testcontainers library

Describe the solution you'd like
Allow to pass Docker.DotNet.Credentials object as parameter

Describe alternatives you've considered
There is no chance to connect to docker with TLS now

Additional context
It's simple change by it would allow user to connect to secured docker api (not only with TLS)
Leave credentials configuration to user exactly as it is done in Docker.DotNet library

I will create PR with changes after submiting this issue to follow contributing rules

I'll close this in favor of #370. There is already an ongoing discussion. Please notice, that the library does not expose models from Docker.DotNet. Here is a short summary about the tasks.
