## Summary of the Pull Request
This is a refactoring of the local debugging.
- The input queue as been abstracted and can now be locally
- The SyncDir can now sync a local directory
- Added the ability to monitor a local directory with a queue
## Reviewers Notes
The most import part of the PR are
- The queue abstraction and implementations
- src/agent/storage-queue/src/azure_queue.rs
- src/agent/storage-queue/src/local_queue.rs
- src/agent/storage-queue/src/lib.rs
- Changes to support local files in
- src/agent/onefuzz/src/syncdir.rs
- Example of how those abstractions are used to link task together
- src/agent/onefuzz-agent/src/local/libfuzzer_fuzz.rs
- src/agent/onefuzz-agent/src/local/common.rs
## Validation Steps Performed
_How does someone test & validate?_
* renames `telemetry_key` to `microsoft_telemetry_key`
* renames `instrumentation_key` to `instance_telemetry_key`
* renames `can_share` to `can_share_with_microsoft`
* renames the `applicationinsights-rs` instances to `internal` and `microsoft` respective of the keys used during construction.
This clarifies the underlying use of Application Insights keys and uses struct tuple to ensure the keys are used correctly via rust's type checker.
This PR adds an experimental "local" mode for the agent, starting with `libfuzzer`. For tasks that poll a queue, in local mode, they just monitor a directory for new files.
Supported commands:
* libfuzzer-fuzz (models the `libfuzzer-fuzz` task)
* libfuzzer-coverage (models the `libfuzzer-coverage` task)
* libfuzzer-crash-report (models the `libfuzzer-crash-report` task)
* libfuzzer (models the `libfuzzer basic` job template, running libfuzzer-fuzz and libfuzzer-crash-report tasks concurrently, where any files that show up in `crashes_dir` are automatically turned into reports, and optionally runs the coverage task which runs the coverage data exporter for each file that shows up in `inputs_dir`).
Under the hood, there are a handful of changes required to the rest of the system to enable this feature.
1. `SyncedDir` URLs are now optional. In local mode, these no longer make sense. (We've discussed moving management of `SyncedDirs` to the Supervisor. This is tangential to that effort.)
2. `InputPoller` uses a `tempdir` rather than abusing `task_id` for temporary directory naming.
3. Moved the `agent` to only use a single tokio runtime, rather than one for each of the subcommands.
4. Sets the default log level to `info`. (RUST_LOG can still be used as is).
Note, this removes the `onefuzz-agent debug` commands for the tasks that are now exposed via `onefuzz-agent local`, as these provide a more featureful version of the debug tasks.
