#5993: Ability to pass args for docker run command during invoke local docker

[endeepak]

What did you implement:

Closes #5993

How did you implement it:

Added new option --docker-arg to pass additional arguments to docker run command used in invoke local --docker

How can we verify it:

serverless.yml

service: debuggable-lambda

provider:
  name: aws
  runtime: nodejs8.10

functions:
  hello:
    handler: handler.hello

handler.js

'use strict';

require('inspector').open(9229, "0.0.0.0", true);

module.exports.hello = async (event) => {
  debugger;
  let var_to_debug = "hello"
  return var_to_debug;
};

.vscode/launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "attach",
            "name": "Attach",
            "port": 9229,
            "localRoot": "${workspaceFolder}",
            "remoteRoot": "/var/task"
        }       
    ]
}

Example steps to debug with Visual Studio Code

• Run below commands

# Create above files in dir called debuggable-lambda
cd debuggable-lambda
# Open code in Visual Studio Code
code .
npm install -g github:endeepak/serverless#feature/5993_invoke_local_docker_arg
serverless invoke local -f hello --docker --docker-arg='-p 9229:9229'

• In Visual Studio Code -> Debug(Left Side Panel) -> Run Attach (Tool Bar)
