Prototype agent installer/upgrader

[kford-newrelic]

Description

Reduce customer friction when installing or upgrading the Java Agent. Ideally would like to:

• [ ] Simplify the downloading of the agent and it's configuration file
• [ ] Where feasible auto modify an application's startup so that the agent runs (via introducing the -javaagent JVM option)
• [ ] Integrate with Fleet Manager/Super Agent but also allow for standalone use

Scope/Assumptions for Prototype:

• Assume tools are available to script (curl, wget, etc)
• Assume one flavor of linux
• Download the agent and yml file and write to a hard coded folder
• Take as inputs:
  • NR license key (prompt if not passed on cmd line)
  • app name (prompt if not passed on cmd line)
• (Stretch) Update sample java app startup with --javaagent

WIP Repo (private): https://github.com/newrelic/prototype-agent-installer

Acceptance Criteria

Prototype implementation.

Design Consideration/Limitations

Currently targeting an executable script based approach (but should also continue brainstorming other options and fleshing them out here)

Dependencies

Must integrate with Fleet Manager/Super Agent.

Additional context

Need to research NR-239240 further too.

A change of direction on the SA/FM PoC has resulting in the script install approach being abandoned. WIP script archived in the private repo mentioned in the description.
