add ability to use attached methods as a lambda handler

[sullirobert]

I’m running into trouble with Registering lambda functions where the registered lambda function is a func attached to a struct. The issues seems be causing cloudFormation to reject the template due to the lambda function name.

here is my deploy log output,

INFO[0010] Registering Sparta function FunctionName=github.com/Scotts-Marketplace/smpb/marketplace/infrastructure/serverless.(_LambdaServer).HandleRequest-fm
...
ERRO[0017] ValidationError: Template format error: Resource name githubcom/ScottsMarketplace/smpb/marketplace/infrastructure/serverless(_LambdaServer)HandleRequestfmLambda443fd5f4645d1e4b1a7bb60f0ae87f3398dabac1 is non alphanumeric.

as you can see, "(*LambdaServer)” is getting added automatically, and contains the bad chars
