Podman

Bugfixes
- Updated Buildah dependency to fix several bugs in `podman build`

Misc
- Small performance improvement in image handling code to not recalculate digests

Features
- Added `--interval` flag to `podman wait` to determine the interval between checks for container status
- Added a switch in `libpod.conf` to disable reserving ports for running containers. This lowers the safety of port allocations, but can significantly reduce memory usage.
- Added ability to search all the contents of a registry if no image name is specified when using `podman search`

Bugfixes
- Further fixes for sharing of UTS namespaces within pods
- Fixed a deadlock in containers/storage that could be caused by numerous parallel Podman processes.
- Fixed Podman running into open file limits when many ports are forwarded
- Fixed default mount propagation on volume mounts
- Fixed default mounts under /dev remaining if /dev is bind-mounted into the container
- Fixed rootless `podman create` with no command specified throwing an error

Misc
- Added `podman rm --volumes` flag for compatability with Docker. As Podman does not presently support named volumes, this does nothing for now, but provides improved compatability with the Docker command line.
- Improved error messages from `podman pull`

Bugfixes
- Added support for configuring iptables and firewalld firewalls to allow container traffic. This should resolve numerous issues with network access in containers.

Note
It is recommended that you restart your system firewall after installing this release to clear any firewall rules created by older Podman versions. If port forwarding to containers does not work, it is recommended that you restart your system.

Features
- Added initial support for the `podman pod` command as non-root

Bugfixes
- Fixed regression where invalid Podman commands would still cause a clean exit
- Fixed `podman rmi --all` to not error if no images are present on the system
- Fixed parsing of container logs with `podman logs` to properly handle CRI logging, fixing some issues with blank lines in logs
- Fixed a bug creating pod cgroups using the systemd cgroup driver with systemd versions 239 and higher
- Fixed handling of volume mounts that overlapped with default container mounts (for example, `podman run -v /dev/:/dev`)
- Fixed sharing of UTS namespace in pods

Misc
- Added additional debug information when pulling images if `--log-level=debug` is specified
- `podman build` now defaults to caching intermediate layers while building

Features
- Added the `podman pod top` command
- Added the ability to easily share namespaces within a pod
- Added a pod statistics endpoint to the Varlink API
- Add information on container capabilities to the output of `podman inspect`

Bugfixes
- Fixed a bug with the --device flag in `podman run` and `podman create`
- Fixed `podman pod stats` to accept partial pod IDs and pod names
- Fixed a bug with OCI hooks handling `ALWAYS` matches
- Fixed a bug with privileged rootless containers with `--net=host` set
- Fixed a bug where `podman exec --user` would not work with usernames, only numeric IDs
- Fixed a bug where Podman was forwarding both TCP and UDP ports to containers when protocol was not specified
- Fixed issues with Apparmor in rootless containers
- Fixed an issue with database encoding causing some containers created by Podman versions 0.8.1 and below to be unusable.

Compatability:
We switched JSON encoding/decoding to a new library for this release to address a compatability issue introduced by v0.8.2. However, this may cause issues with containers created in 0.8.2 and 0.8.3 with custom DNS servers.
