Make sure there is no unnecessary delays when there are multiple reports in the queue.
This change also adds a test for the custom LB policy.

Based on [OpenTelemetry Metrics gRFC](https://github.com/grpc/proposal/blob/master/A66-otel-stats.md#opentelemetry-metrics), we should recored unregistered RPC method name as `other`, this PR adds the ability to pass register method information when creating a call.
We'll consider calls created using generated stubs as registered, note that this won't prevent user from setting `registered_method=True` when creating calls manually.
This is also enabled for simple stub flow but **NOT enabled for AsyncIO**, we'll add that later when start working on AsyncIO Observability.

Eventually for call-v3 we're going to want to have registration of filters generate the appropriate glue into the channel runtime to execute a call.
Begin that process now and gradually by introducing the new syntax and allowing a piecemeal migration to it - by the time we're done converting filters to the v3 APIs we'll also have the registration piece done.

We encountered an api_fuzzer test case that adds a huge number of addresses that all immediately fail to connect, but it set max_backoff to 0, so there was a giant busy loop where pick_first was constantly trying to connect to subchannels with no delay. The FuzzingEventEngine was getting stuck in a tick loop, always accumulating more tasks that needed to be executed immediately, so it could never make forward progress on the test case.
This PR fixes the problem by adding a fixed 1us delay if the task's delay is 0 and the test case has not provided any more fixed delays.
(Unfortunately, I cannot include the test case that triggered the problem in this PR, because it winds up exceeding the RBE stdout limit.)
Fixes b/310664846.

This reverts commit 96b9e8d3e3.
[Implement OpenTelemetry PR](https://github.com/grpc/grpc/pull/35292) was [reverted](96b9e8d3e3) because some tests started failing after import the changes to g3.
After investigation, we found root cause, it can be fixed both on our side and on gapic API side, we opened an issue to [gapic API team](https://github.com/googleapis/python-api-core/issues/579), this PR will includes the fixes on our side.

Continue supporting the current grpc-testing that I suppose is used
inside of Google, but also allow to configure a different project to
upload results to.
The format "project_id.dataset_id.table_id" is common for BigQuery so it
seems idiomatic to do it in this way. Adding a separate command line
option would be more complicated because it would require changes all
the way down the chain (at least in the entry point for the test driver
and in the LoadTest controller).

This PR adds CSM Observability testing capability in the PSM Interop testing framework. This PR mostly changes the framework Python code.
This adds a flag `enable_csm_observability` to the client / server deployment yaml file such that, when enabled, we will create a GMP `PodMonitoring` resource and pass the `--enable_csm_observability` to each language's client / server container (for them to actually enable the Prometheus endpoint)
I added a new test under `tests/csm/csm_observability_test.py`. This is basically a copy of the `tests/baseline_test.py` but with the `enable_csm_observability=True`.
Other PRs for this whole thing to work:
- https://github.com/grpc/grpc/pull/34752: The `PodMonitoring` resource yaml template
- https://github.com/grpc/grpc/pull/34832: Support for the `--enable_csm_observability` flag in the C++ client/server image

Remove the old `switch` library - this used to be an implementation detail of `Seq`, `TrySeq` - but has become unused.
Add a new user facing primitive `Switch` that fills a similar role to `switch` in C++ - selecting a promise to execute based on a primitive discriminator - much like `If` allows selection based on a boolean discriminator now.
A future change will optimize this to actually lower the `Switch` into an actual `switch` statement, but for right now I want to get the functionality in.

Provide a public experimental API and bazel compatible build target for OpenTelemetry metrics.
Details -
* New `OpenTelemetryPluginBuilder` class that provides the API specified in https://github.com/grpc/proposal/blob/master/A66-otel-stats.md
* The existing `grpc::internal::OpenTelemetryPluginBuilder` class is moved to `grpc::internal::OpenTelemetryPluginBuilderImpl` for disambiguation.
* Renamed `OTel` in some instances to `OpenTelemetry` for consistency.
