PoC for auto-generated TOML examples from structs

[skudasov]

---

Below is a summarization created by an LLM (gpt-4-0125-preview). Be mindful of hallucinations and verify accuracy.

Why

The changes introduce a new command called tomldoc within the Chainlink Testing Framework. This command generates TOML documentation for various configuration structs used within the framework, such as blockchain networks and Chainlink node sets. It does this by reflecting over the structs, initializing them, and then using a TOML encoder to write out documentation with comments that describe each field. This automation facilitates the creation of accurate and up-to-date configuration examples for users of the framework.

What

• New file: framework/cmd/tomldoc/go.mod
  Initializes a new Go module specifically for the tomldoc command. It includes dependencies necessary for the command to function, such as the TOML encoder and the testing framework itself.
• New file: framework/cmd/tomldoc/go.sum
  Contains the expected cryptographic checksums of the dependencies defined in go.mod, ensuring the integrity of the module's dependencies.
• New file: framework/cmd/tomldoc/main.go
  Implements the logic of the tomldoc command. It uses reflection to initialize the configuration structs and then encodes them to TOML, including comments that serve as documentation for each field in the struct.
• New file: framework/cmd/tomldoc/toml-docs.toml
  An example output of the tomldoc command. It serves as a template or documentation for the TOML configuration of the Chainlink Testing Framework.
• Modified file: framework/components/blockchain/blockchain.go
  Adds comments to the Input struct fields. These comments are used by the tomldoc command to generate documentation.
• Modified file: framework/docker.go
  Adds comments to the ContainerResources struct fields for documentation purposes.
