// <summary>
// This method initializes status,ssh,hooks & deployment locks used by Kudu to ensure
// synchronized operations. This method creates a dictionary of locks which is injected
// into various controllers to resolve the locks they need.

// <remarks>
// Uses File watcher.
// This originally used Ninject's "WhenInjectedInto" in .Net project for specific instances. IServiceCollection
// doesn't support this concept, or anything similar like named instances. There are a few possibilities,
// but the hack solution for now is just injecting a dictionary of locks and letting each dependent resolve
// the one it needs.
