For #23750
# Overview
This PR adds a basic tool for creating and restoring Fleet dev
snapshots. In this first iteration a snapshot is just a folder
containing a MySQL db dump made using the existing backup/restore
scripts, and the tool allows you to easily save and restore snapshots
interactively.
## Usage
* `make snapshot` to create a new snapshot
* `make restore` to select and restore a snapshot
## Future plans
Future iterations can add metadata to snapshots to integrate things
like:
* node keys from osquery-perf, so you can easily reconnect to hosts
created in a previous session
* env vars from when the snapshot was made
* the branch from when the snapshot was made, to allow switching to that
branch and restarting the server as part of the restore process
*
