MAINT BREAK: Adding Attack Technique Abstraction

[rlundeen2]

Modifying the AttackTechnique abstraction, which contains a SeedTechniqueGroup and an attack, encapsulates the entire piece of an attack that we'll measure success with.

This PR

• Adds an identifier to the AttackTechnique class, which is Identifiable
• Adds the identifier to the AtomicAttackResultIdentity in AttackResult
• Adds AttackTechnique as the way to call AtomicAttacks
• Seed merging is added so techniques can be combined into an AttackSeedGroup
• Scenarios are updated to use this as a pattern when creating AtomicAttacks

After this, we'll include an AttackTechniqueRegistry which can query attacks in a reusable way, and scenarios can use the shared registry for attack strategies.

Breaking:

It breaks some memory queries, but only from very recent PRs
