v0.3.0

Added

• version command for both ncctl and ncserver: prints the semantic version, commit hash, and build date; build-time values are injected via -ldflags and fall back to embedded VCS info when built from source

Changed

• Update documentation for ncserver
• Split documentation for ncctl and nccserver

Fixed

• servers power commands, now support lower case value (e.g. on, off)
• interfaces create-vlan and interfaces update now accept lowercase --driver values (e.g. virtio)
