Since the basic format of cluster, host and guest firewall
configurations is the same, we create a generic parser that can handle
the common config format. The main difference is in the available
options, which can be passed via a generic parameter.

Additionally we implement FromStr for all rule types and parts, which
can be used for parsing firewall config rules. Initial rule parsing
works by parsing the different options into a HashMap and only then
de-serializing a struct from the parsed options.
This intermediate step makes rule parsing a lot easier, since we can
reuse the deserialization logic from serde. Also, we can split the
parsing/deserialization logic from the validation logic.

Currently this is parsing the config files via the filesystem. In the
future we could also get this information from pmxcfs directly via
IPC which should be more performant, particularly for a large number
of VMs.

Adds types for log and (log-)rate-limiting firewall config options as
well as FromStr implementations for parsing them from the config.
