config: add starlark config support Handle `.agola/config.star` files in starlark config format. To provide a context like done for jsonnet we require that the starlark agola config file contains a main function that will receive a config context as a dict. We also had to implement our own json conversion from a starlark dict since go starlark removed its own function.

*: use new errors handling library Implement a new error handling library based on pkg/errors. It provides stack saving on wrapping and exports some function to add stack saving also to external errors. It also implements custom zerolog error formatting without adding too much verbosity by just printing the chain error file:line without a full stack trace of every error. * Add a --detailed-errors options to print error with they full chain * Wrap all error returns. Use errors.WithStack to wrap without adding a new messsage and error.Wrap[f] to add a message. * Add golangci-lint wrapcheck to check that external packages errors are wrapped. This won't check that internal packages error are wrapped. But we want also to ensure this case so we'll have to find something else to check also these.
