GetCapabilities returns the server capabilities configuration of the

### Method Details

`getCapabilities(instanceName, x__xgafv=None)`

    GetCapabilities returns the server capabilities configuration of the
    remote endpoint.
    Only the capabilities of the services supported by the endpoint will
    be returned:
    * Execution + CAS + Action Cache endpoints should return both
      CacheCapabilities and ExecutionCapabilities.
    * Execution only endpoints should return ExecutionCapabilities.
    * CAS + Action Cache only endpoints should return CacheCapabilities.

    Args:
      instanceName: string, The instance of the execution system to operate against. A server may
    support multiple instances of the execution system (with their own workers,
    storage, caches, etc.). The server MAY require use of this field to select
    between them in an implementation-defined fashion, otherwise it can be
    omitted. (required)
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:
