Syntax doesn't fly well with other plugins

Some other Serverless plugins cleanup their strings from special characters, as can be seen here: https://github.com/sbstjn/serverless-dynamodb-autoscaling/blob/master/src/aws/name.ts#L14

What do you think about the following solution?

1. Hook in an earlier stage (after the parsing of Serverless variables), and replace this plugin's syntax inside the parsed Serverless config with something like cfvarsrandomrandom, while creating a map of which random pattern referred to which cf vars syntax.
2. In the current hook, look for these random patterns in the template and use the cf vars syntax from the mapping.
