        In order to execute an action, the client must first upload all of the
        inputs, the
        Command to run, and the
        Action into the
        ContentAddressableStorage.
        It then calls `Execute` with an `action_digest` referring to them. The
        server will run the action and eventually return the result.
        
        The input `Action`'s fields MUST meet the various canonicalization
        requirements specified in the documentation for their types so that it has
        the same digest as other logically equivalent `Action`s. The server MAY
        enforce the requirements and return errors if a non-canonical input is
        received. It MAY also proceed without verifying some or all of the
        requirements, such as for performance reasons. If the server does not
        verify the requirement, then it will treat the `Action` as distinct from
        another logically equivalent action if they hash differently.
        
        Returns a stream of
        google.longrunning.Operation messages
        describing the resulting execution, with eventual `response`
        ExecuteResponse. The
        `metadata` on the operation is of type
        ExecuteOperationMetadata.
        
        If the client remains connected after the first response is returned after
        the server, then updates are streamed as if the client had called
        WaitExecution
        until the execution completes or the request reaches an error. The
        operation can also be queried using Operations
        API.
        
        The server NEED NOT implement other methods or functionality of the
        Operations API.
        
        Errors discovered during creation of the `Operation` will be reported
        as gRPC Status errors, while errors that occurred while running the
        action will be reported in the `status` field of the `ExecuteResponse`. The
        server MUST NOT set the `error` field of the `Operation` proto.
        The possible errors include:
        
        * `INVALID_ARGUMENT`: One or more arguments are invalid.
        * `FAILED_PRECONDITION`: One or more errors occurred in setting up the
          action requested, such as a missing input or command or no worker being
          available. The client may be able to fix the errors and retry.
        * `RESOURCE_EXHAUSTED`: There is insufficient quota of some resource to run
          the action.
        * `UNAVAILABLE`: Due to a transient condition, such as all workers being
          occupied (and the server does not support a queue), the action could not
          be started. The client should retry.
        * `INTERNAL`: An internal error occurred in the execution engine or the
          worker.
        * `DEADLINE_EXCEEDED`: The execution timed out.
        * `CANCELLED`: The operation was cancelled by the client. This status is
          only possible if the server implements the Operations API CancelOperation
          method, and it was called for the current execution.
        
        In the case of a missing input or command, the server SHOULD additionally
        send a PreconditionFailure error detail
        where, for each requested blob not present in the CAS, there is a
        `Violation` with a `type` of `MISSING` and a `subject` of
