evaluate if we can support the path matching in handler.yml with or without trailing slash

```
ie:

 Handler.yml:

- path /foo/v1
  - com.networknt.FooHandler

API consumer requests /foo/v1/

As it is, this fails to match the path, and so we have had to populate our handler.yml with dual path specs for every API to allow consumers to call our APIs with or without trailing slashes.  This is a nuisance and it would be great if we could auto-match these.

```
