`podman kube play` can create pods and containers from YAML
read from a URL poiniting to a YAML file.
For example: `podman kube play https://example.com/demo.yml`.
`podman kube down` can also teardown pods and containers created
from that YAML file by also reading YAML from a URL, provided the
YAML file the URL points to has not been changed or altered since
it was used to create pods and containers

the env vars are held in the spec rather than the config, so they need to be mapped manually. They are also of a different format so special handling needed to be added. All env from the parent container will now be passed to the clone.

This exposed a nasty bug in our system-test setup: Ubuntu (runc)
was writing a scratch containers.conf file, and setting CONTAINERS_CONF
to point to it. This was well-intentionedly introduced in #10199 as
part of our long sad history of not testing runc. What I did not
understand at that time is that CONTAINERS_CONF is **dangerous**:
it does not mean "I will read standard containers.conf and then
override", it means "I will **IGNORE** standard containers.conf
and use only the settings in this file"! So on Ubuntu we were
losing all the default settings: capabilities, sysctls, all.
Yes, this is documented in containers.conf(5) but it is such
a huge violation of POLA that I need to repeat it.
In #14972, as yet another attempt to fix our runc crisis, I
introduced a new runc-override mechanism: create a custom
/etc/containers/containers.conf when OCI_RUNTIME=runc.
Unlike the CONTAINERS_CONF envariable, the /etc file
actually means what you think it means: "read the default
file first, then override with the /etc file contents".
I.e., we get the desired defaults. But I didn't remember
this helpers.bash workaround, so our runc testing has
actually been flawed: we have not been testing with
the system containers.conf. This commit removes the
no-longer-needed and never-actually-wanted workaround,
and by virtue of testing the cap-drops in kube generate,
we add a regression test to make sure this never happens
again.
It's a little scary that we haven't been testing capabilities.
Also scary: this PR requires python, for converting yaml to json.
I think that should be safe: python3 'import yaml' and 'json'
works fine on a RHEL8.7 VM from 1minutetip.

Followup to #14613, which was never actually tested until this
week in RHEL8 gating tests (see issue #15337).
* add missing backslash in '|' expression
* allow extra text after error (e.g., "invalid argument")
No way to test this until it makes its way into RHEL8,
so, fingers crossed.

`podman-remote manifest push` has shown absolutely no progress at all.
Fix that by doing the same as the remote-push code does.
Like remote-push, `quiet` parameter is true by default for backwards

Integrate sd-notify policies into `kube play`. The policies can be
configured for all contianers via the `io.containers.sdnotify`
annotation or for indidivual containers via the
`io.containers.sdnotify/$name` annotation.
The `kube play` process will wait for all containers to be ready by
waiting for the individual `READY=1` messages which are received via
the `pkg/systemd/notifyproxy` proxy mechanism.
Also update the simple "container" sd-notify test as it did not fully
test the expected behavior which became obvious when adding the new
tests.

The notify socket can now either be specified via an environment
variable or programatically (where the env is ignored). The
notify mode and the socket are now also displayed in `container inspect`
which comes in handy for debugging and allows for propper testing.

implement new ssh interface into podman
this completely redesigns the entire functionality of podman image scp,
podman system connection add, and podman --remote. All references to golang.org/x/crypto/ssh
have been moved to common as have native ssh/scp execs and the new usage of the sftp package.
this PR adds a global flag, --ssh to podman which has two valid inputs `golang` and `native` where golang is the default.
Users should not notice any difference in their everyday workflows if they continue using the golang option. UNLESS they have been using an improperly verified ssh key, this will now fail. This is because podman was incorrectly using the
ssh callback method to IGNORE the ssh known hosts file which is very insecure and golang tells you not yo use this in production.
The native paths allows for immense flexibility, with a new containers.conf field `SSH_CONFIG` that specifies a specific ssh config file to be used in all operations. Else the users ~/.ssh/config file will be used.
podman --remote currently only uses the golang path, given its deep interconnection with dialing multiple clients and urls.
My goal after this PR is to go back and abstract the idea of podman --remote from golang's dialed clients, as it should not be so intrinsically connected. Overall, this is a v1 of a long process of offering native ssh, and one that covers some good ground with podman system connection add and podman image scp.
