Requirement for live agent

[kaylakraines]

Description

This PR provides a new requirement to only run an ability if the agent paw referenced in the ability matches a currently live agent.
This feature was developed to enable the Turla port to only run an ability if the implant that will be tasked in that ability is actively beaconing in to the server.

This PR is associated with center-for-threat-informed-defense/adversary_emulation_library#151

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

Tested on both the Turla (Snake) & Turla (Carbon) adversaries. Observed abilities running if the required implant/agent was listed as a live agents, and not running if it was not listed as a live agent.

@kaylakraines The linked repo is private - it would be better to link to the PR to CTID's AEL once you've created it.

It also looks like there's still one failing check with python 3.7

Will do @mchan143

@clenk is working on this because Caldera no longer supports Python 3.7
