These functions and types are shallow wrappers around the context store and were intended for internal use as implementation for the CLI itself. They were exported in3126920af1to be used by plugins and Docker Desktop. However, there's currently no public uses of this, and Docker Desktop does not use these functions. These were deprecated in95eeafa551and are no longer used. This patch removes the deprecated functions as they were meant to be implementation specific for the CLI. If there's a need to provide utilities for manipulating the context-store other than through the CLI itself, we can consider creating an SDK for that purpose. This removes: - `RunCreate` and `CreateOptions` - `RunExport` and `ExportOptions` - `RunImport` - `RunRemove` and `RemoveOptions` - `RunUpdate` and `UpdateOptions` - `RunUse` Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
