Add per command cgroup manager option

[mgjm]

What type of PR is this?

/kind feature

What this PR does / why we need it:

The CgroupManager option is only used inside createContainer and execSyncContainer.

This PR moves this option from the global config to the respective command options.

For backwards compatibility the go client keeps the global option and only uses the per command option if the global ConmonServerConfig.CgroupManager is set to CgroupManagerPerCommand.

This allows existing users like CRI-O to keep working with old and new conmon-rs servers and will allow new users like podman to use the per command option with new conmon-rs servers.

Which issue(s) this PR fixes:

None

Special notes for your reviewer:

This PR depends on #1499 because capnp fields are numbered sequentially. Merged

Clippy complained about too many arguments to the generate_create_args and generate_exec_sync_args functions. Therefore I moved the common arguments to the new GenerateRuntimeArgs struct and implemented the create_args and exec_sync_args methods.

Does this PR introduce a user-facing change?

Add option to specify the cgroup manager per command
