Log Dynamodb Local errors to console

Currently dynamodb-localhost plugin(Dependency to serverless-dynamodb-local) doesn't include error logs coming from dynamodb local to the console. This needs to be implemented, listening to console output from dynamodb local process.

Reference https://github.com/99xt/dynamodb-localhost/blob/master/index.js

Start with the referenced index.js in the dynamodb-localhost plugin and trace how the dynamodb-local process is started and how its output is handled. Confirm the expected console behavior by running the local plugin; done means errors emitted by the DynamoDB Local process are visible in the console.
