Describe the bug

Luis:build

1. Luis:build and qnamaker:build do not write .dialog if no –out is specified.
2. –suffix when not specified resulted in LUIS app with (Undefined).
3. Verify luis:build detects changes to references.
4. Fix issue with config relative path. Relative path must always be relative to the CWD()5
5. C:\users\temp> bf luis:build –in . –out generated –config ..\foo.config.json

Luis:cross-train

1. -- config is relative to –in and not relative to the pwd()
2. Cross-train config is file name case sensitive.
3. Cross-train should only copy over files specified in the cross-train config to output but all references should be fully resolved before they are copied over.
4. QnA meta-data property is not applied to references
5. Apply cross-train for .lu and .qna documents after fully resolving imports.
6. If multiple source .lu or .qna files are pulling in the same reference, the for QnA, meta-data pairs need to be added to the same QnA pair (e.g. root as well as dialog A pulling in some chitchat utterances)

Qnamaker:build

1. There is no way to get endpoint key. We should print this on screen. Note the endpoint key is different from authoring key and I believe is per KB – need to verify and resolve.
2. Fix issue with config relative path. Relative path must always be relative to the CWD()
