Breaking change

• backend will be consumed by proxy and request as transport configuration now. The previous behaviour
  that backend represents a proxy functionality is removed. Also the backend block must be defined in
  definitions, proxy or request.
  • Config migration, add a proxy block:

  endpoint "/old" {
    backend = "reference"
    # or
    backend {
      #...
    } 
  }
  # change to:
  endpoint "/new" {
    proxy {
      backend = "reference"
    }
    # or
    proxy {
      backend {
        #...
      }
    }
  }

Change

• Client-Request and upstream response body buffering by default
• Server shutdown delay and deadline defaults to 0s now and can be configured via env if required
• Websocket connection upgrades in combination with proxy {} are disabled
  • we will add a proxy option for ws usage later on

Bug Fixes

• An absolute path resolving for *_file configuration attributes (#120)

Features

• Endpoint:
  • Add proxy block to reverse proxy the client request to the configured backend.
  • Add request block to send a simple upstream request. Docs
  • Add response block to create a custom client response. Docs
• Add jwt_sign() function to be able to create and sign a token with a jwt_signing_profile. Docs (#112)
• Add unixtime() function for the current unix time in seconds (#124)

Code Refactoring

• underlying code structure to represent an endpoint block with proxy, request and response configuration
• hcl evaluation context as own 'container' with context.Context interface
• test cleanups

Dependencies

• build with go 1.16
• logrus to v1.8.1
