Add generic software-package, service, and container object templates

[adulau]

Motivation

• Add first-class MISP object templates to represent software packages and their state and to cover container-related telemetry and runtime/network context as requested in the linked issues (Add software package object #331, MISP Object Proposal: Service Object #492, MISP Object Proposal: container-image #493, MISP Object Proposal: container-instance #494, MISP Object Proposal: container-network #495).
• Provide structured attributes for DFIR and supply-chain use cases (image digest/signature, image metadata, container runtime details, container networking, and service/process context).

Description

• Added five new object templates: objects/software-package/definition.json, objects/service/definition.json, objects/container-image/definition.json, objects/container-instance/definition.json, and objects/container-network/definition.json, each with a dedicated uuid, version, meta-category, and requiredOneOf definitions.
• software-package captures name, version, vendor, state (sane defaults valid/backdoored/unknown) and descriptive metadata.
• service models name, port(s), function, and command-line with requiredOneOf on name or command-line.
• container-image stores image-name, tag, digest, registry, architecture, os, created, size, layers, labels, and signature.
• container-instance captures runtime fields such as container-id, image, command, lifecycle timestamps (created/started/finished), state, networking (ip-address, ports, network-mode), privileges/capabilities, mounts, and environment-variables.
• container-network provides network-name, driver, subnet, gateway, connected-containers, internal flag, and dns entries tailored for container networks.

Testing

• JSON syntax/validation for the new files was checked with jq empty on each file and returned OK.
• Repository object formatting was applied by running ./jq_all_the_things.sh successfully to normalize object JSON.
• Full repository validation with ./validate_all.sh failed in this environment due to a missing helper binary (uuidparse) used by the validation scripts, which prevented a complete validate_all run.
