Support `uri` with and without `//`

[lordrip]

Please describe the feature that you want to propose

Currently, Kaoto honors the syntax field of components, and some components do not use // as a delimiter while still supporting it.

Example of this is are ftp and sftp components:

    "syntax": "ftp:host:port\/directoryName",

Notice how // it's not included in the syntax but still a user could write the URI as:

uri: ftp://myHost:myPort/dirName # (not supported by Kaoto)

# vs

uri: ftp:myHost:myPort/dirName # (supported by Kaoto)

The goal is to have support for uris using // delimiter, even if not specified in the syntax field.
