refactor: remove TOML config and related changes

[mmalenic]

Closes umccr/htsget-rs#294 and umccr/htsget-rs#295.

I figured this would be a good spot to wrap up this PR.

Changes

• Simplifies settings logic by removing TOML config files.
  • Boolean parameters like lookupHostedZone, copyExampleKeys, copyTestData, public are simplified. copyTestData now copies both test files and keys. lookupHostedZone is resolved based on the whether a hostedZone parameter is passed in, and public is determined based on the jwt
  • Features automatically resolve, with the option to specify cargoLambdaFlags manually.
• Locations can now be configured using the simple location syntax. Advanced options can be specified using a environmentOverride parameter, whereas CORS and service-info are configured using separate properties.
  • Locations are automatically derived if using copyTestData.
• Other minor fixes related to deployment logic and resolvers.
• Added eslint and typedoc for documentation table generation.
• Removed docker as it's part of htsget-rs.
• Reworded documentation and deployment instructions.
