Don't attempt to remove unsupported resources on older daemon
When running `docker stack rm <some stack>` against an older daemon,
a warning was printed for "configs" being ignored;

    WARNING: ignoring "configs" (requires API version 1.30, but the Docker daemon API version is 1.26)

Given that an old daemon cannot _have_ configs, there should not be
a need to warn, or _attempt_ to remove these resources.

This patch removes the warning, and skips fetching (and removing)
configs.

A check if _secrets_ are supported by the daemon is also added,
given that this would result in an error when attempted against
an older (pre 1.13) daemon.

There is one situation where this could lead to secrets or
configs being left behind; if the client is connecting to a
daemon that _does_ support secrets, configs, but the API version
is overridden using `DOCKER_API_VERSION`, no warning is printed,
and secrets and configs are not attempted to be removed.

Given that `DOCKER_API_VERSION` is regarded a feature for
debugging / "power users", it should be ok to ignore this.
