bitbake: toaster: bitbake cooker log saving and downloading

This patch brings in cooker log saving and proper download links.

* toasterui will now write the cooker log file if running in managed
mode
* the BuildRequest has a new state, REQ_ARCHIVE, indicating that the
build is completed, and the artifacts are ready to be grabbed
* the runbuild test execution commands will gather needed artifacts,
and save them to a storage directory selected during Toaster setup.
* the build dashboard, project builds and all builds pages have
permanent links for the cooker log
