Serverless Vpc Plugin Versions Save

Fixed #483 - thanks for reporting @PetroccoCo!

BREAKING CHANGES

• Renamed LambdaExecutionSecurityGroup to AppSecurityGroup
• The AppSecurityGroup only allows HTTPS ingress and egress by default
  • If an S3 VPC Endpoint is created, AppSecurityGroup also allows HTTP egress just to S3
• The VPC default security group's egress rule is modified to only permit outbound access to itself (see Remove Default Rule)
• Removed the LambdaEndpointSecurityGroup security group in favor of using the AppSecurityGroup for VPC Interface Endpoints

NEW FEATURES

• Ability to create SSM parameters by specifying createParameters: true in the custom.vpcConfig options (see example usage)
• A DHCPOptionsSet is now created and attached to the VPC

OTHER CHANGES
