Kiln should support bake command with local bosh tarball file

[seanpang-vmware]

Is your feature request related to a problem? Please describe.

In internel projects, when generating tiles, the bosh tarball file maybe generated locally, that is not released to github or S3, due to product policy or product dependencies requirements, In this case, when using kiln bake it should support adding a parameter to indicate local file instead forcibly fetching files from remote end.

Describe the solution you'd like

add a parameter for kiln bake command, eg: --release-directory to provide local bosh tarball file.

Describe alternatives you've considered

there is no alternative way.
