Plugin request - [Serverless]

[PhillypHenning]

Is your feature request related to a problem? Please describe. To broaden our support for IaC options I'd like to request that a serverless plugin is created for bitops:v2.0.1

Additional context This should be done sooner rather then later and will use the bitovi/battleship-api initiative as a "use-case"

Here is the slsdeploy script that I created in my previous job...

#!/bin/bash
# *************************************************************************************************** #
#
#   Bash script to recursively run sls deploy
#
#   The script requires the following *MANDATORY* configuration parameters to be supplied as command
#   line arguments:
#       -profile:       AWS Profile
#       -region:        AWS region
#       -subsystem      crmjs
#
#   The following configuration parameters are optional:
#       -stage: Stage to deploy to, default stage is 'default'
#
#
#   Ex: ./slsdeploy.sh -profile asurion-dev.xxxxxx -region us-east-1 -stage sqa
#
# *************************************************************************************************** #

declare AWS_PROFILE
declare SERVICE_STAGE
declare SUBSYSTEM
declare FUNCTIONS_LIST

SCRIPTPATH="$( cd "$(dirname "$0")" ; pwd -P )"

# *************************************************************************************************** #
# Recurse thru folders and run sls deploy.
#
# Expected folder structure
#   ../infrastructure               Common artifacts
#   ../infrastructure/functions     Common functions, like Custom Authorizer
#   ../functions                    Parent folder for all functions; To-Do: Dependency
#
# Arguments:
#   None
# Returns:
