Invoke lambda_handler with event argument

[manycoding]

Context

There's no way to call lambda_handler in the same manner as AWS Lambda test for non-wsgi apps.
Related to #2146 #983

Expected Behavior

I wanna get an output from the specified lambda_handler function with specified event argument.

zappa invoke dev {"address":"5760 Teredo St., Sechelt, BC, Canada, VON 3A"}

{
  "parsed_address": {
    "street_address": "5760, Teredo St.",
    "city": "Sechelt",
    "state": "BC",
    "postcode": "VON 3A0",
    "country": "Canada"
  }
}

Actual Behavior

Nothing. In fact I cannot get any output even for raw commands:
zappa invoke dev 'print("hey")' --raw

Executing a test event from Lambda UI works as expected.

Possible Fix

Allow to

Steps to Reproduce

1. Create a lambda_handler function with event and context
2. Specify it in zappa_settings
3. Zappa invoke from cli
