This adds a `resend_on_reset` flag to the `send_params()` method that
enables parameters to be resent immediately after a service is
reset. This is required by the LLVM environment to ensure that the
runtime observation parameters are sent before the reward space is
reset.

Fixes #756.

These are typically raised from transative dependencies.

The __slots__ attribute is not compatible with copy() operator.

Fixes #768.

These tests require extra build steps which are performed in the
regular examples jobs.

This is to prevent an incompatibility between older versions of gym
and importlib-metadata.

Addresses deprecation warnings from Github actions runner.

This is to fix a generic warning from gym library:

    UserWarning: WARN: The environment example-v0 is out of date. You
    should consider upgrading to version `v1` with the environment ID
    `example-v1`.

Mitigates warnings:

    WARN: Overriding environment example-v1

At this point 3.6 is quite lagging in features and some of
dependencies have dropped support for it.
