Initial implementation of simplifying config interfaces

[jlaneve]

Description

Over time, we've continued adding parameters everywhere without giving much thought to the interface. This PR aims to simplify the interface for working with Cosmos DAGs/Task Groups and operators by collapsing the arguments into four config objects:

• ProjectConfig: parameters that Cosmos needs to understand where your dbt project is
• RenderConfig: parameters to tell Cosmos how to render your dbt project as a DAG
• ExecutionConfig: parameters to tell Cosmos how to execute your dbt project
• ProfileConfig: parameters to tell Cosmos what to run your dbt against

You can see the exact parameters each config takes here: https://github.com/astronomer/astronomer-cosmos/blob/simplify-interface/cosmos/config.py

It also:

• simplifies the dbt_project_name and dbt_root_path arguments into a single arg
• removes dbt_args, which was a duplicate of operator_args

closes #372

Breaking Change?

Yes, the parameters to the DAG/Task Group and operators change. This is an intentional breaking change before the 1.0 release.
