OneDeploy API - /publish and /api/publish (Azure-App-Service#134)
* OneDeploy API - /publish and /api/publish - Adds a new /publish and /api/publish APIs for Java deployment scenarios - This new API primarily supports Java scenarios currently, but can be easily extended for additional scenarios - Overview of new changes - OneDeploy reuses bulk of the code from PushDeploymentController and DeploymentManager - OneDeployBuilder is a new OneDeploy specific site builder, OneDeployFetch is a OneDeploy specific Fetch handler - WatchedFileEnabled/RestartAllowed/ArtifactType/TargetRootPath are additional knobs introduced in DeploymentInfoBase.cs for OneDeploy specific functionality - The implementation inspects the WEBSITE_STACK environment variable for certain scenarios. This variable is injected by the App Service runtime - OneDeploy uses the new restart API (in other words, it does not rely on touching any file for triggering a recycle) - Summary of changes to existing code: - A bunch of variables were renamed for readability purposes - ZipDeploymentInfo is now ArtifactDeploymentInfo (generalized) and is now used by OneDeploy for non-zip artifacts as well - Note: This is primarily a port of projectkudu/kudu#3203 with some additional enhancements to OneDeploy. These enhancements will be back ported to https://github.com/projectkudu/kudu * Minor refactoring
