Adding --watches and --project flags to jf rt mvn command when scanning

[dortam888]

Problem Description:
When scanning local file system artifacts before uploading them from a build using jf rt mvn --scan, Currently JFrog CLI will use jf scan with a --repo-path flag by default. The repo-path will be the repo-deploy-release that is configured with mvnc command.
In case repo-deploy-release is defined as a virtual repository Xray will use it as the repo-path but won't find any watches on it since a virtual repository can't be indexed in Xray and therefore can't be configured for watches.

Feature Description:
Instead of using the default repo-path add --watches and --project to jf rt mvn when using --scan flag, like in jf scan command, so it can be used to scan artifacts for violations when using a virtual repository as the deploy repository.
