This commit adds support for using CIDR blocks defined in the `no_proxy`
environment variable. For example:
```
http_proxy=http://localhost:8080 no_proxy=10.10.0.0/24
```
The example above would bypass the proxy if the server IP matched
10.10.0.0 - 10.10.0.255.
Closes#22681

Perf shows that the memory are accessed twice for call->wrapped in
startBatch. If we assign call->wrapped to a variable and then use it in
startBatch, only one memory access is needed. Then, the second
attempting to get the value of call->wrapped will be done via register.

Fix-forward for https://github.com/grpc/grpc/pull/32629. Referencing the
[documentation](https://github.com/marketplace/actions/labeler), if the
top-level list for a label is a list of strings, it is treated as a
single `any` entry. `any` entries are ANDed together. This means that
the original PR said "label lang/python if anything _besides_
grpc_core_dependencies.py changed." This is obviously not desired.
This PR makes the `any` explicit. The logic now says "label lang/python
if any of these few files has changed OR if any file but
grpc_core_dependencies.py under src/python has changed."
I'm still not 100% certain that this will work, but the stakes aren't
super high.

Add the capability for api-fuzzer to fuzz over different config
variables, to enable us to spot incompatible configurations there
sooner.

The logic is straightforward: attempt to read the
`GRPC_ALTS_MAX_CONCURRENT_HANDSHAKES` environment variable and, if it
set to an integer, instantiate the handshake queues based on this
integer.
Based on go/grpc-alts-concurrent-handshake-cap.
Protobuf's HEAD has changed the layout of bazel targets we use for
getting the list of source files for our python grpcio.tools build.
With this patch, make_grpcio_tools.py finishes successfully and gives
reasonable results.
Change was created by the release automation script. See
go/grpc-release.

Implement listeners, connection, endpoints for `FuzzingEventEngine`.
Allows the fuzzer to select write sizes and delays, connection delays,
and port assignments.
I made a few modifications to the test suite to admit this event engine
to pass the client & server tests:
1. the test factories return shared_ptr<> to admit us to return the same
event engine for both the oracle and the implementation - necessary
because FuzzingEventEngine forms a closed world of addresses & ports.
2. removed the WaitForSingleOwner calls - these seem unnecessary, and we
don't ask our users to do this - tested existing linux tests 1000x
across debug, asan, tsan with this change
Additionally, the event engine overrides the global port picker logic so
that port assignments are made by the fuzzer too.
This PR is a step along a longer journey, and has some outstanding
brethren PR's, and some follow-up work:
* #32603 will convert all the core e2e tests into a more malleable form
* we'll then use #32667 to turn all of these into fuzzers
* finally we'll integrate this into that work and turn all core e2e
tests into fuzzers over timer & callback reorderings and io
size/spacings

(hopefully last try)
Add new channel arg GRPC_ARG_ABSOLUTE_MAX_METADATA_SIZE as hard limit
for metadata. Change GRPC_ARG_MAX_METADATA_SIZE to be a soft limit.
Behavior is as follows:
Hard limit
(1) if hard limit is explicitly set, this will be used.
(2) if hard limit is not explicitly set, maximum of default and soft
limit * 1.25 (if soft limit is set) will be used.
Soft limit
(1) if soft limit is explicitly set, this will be used.
(2) if soft limit is not explicitly set, maximum of default and hard
limit * 0.8 (if hard limit is set) will be used.
Requests between soft and hard limit will be rejected randomly, requests
above hard limit will be rejected.

Adds a simple hello-world example for GCP Observability purposes along
with a README.
The microservices observability user guide is not yet up, but this still
refers to it anyway.

Previously we triggered a flow control update when `announced <
target/2`, but if `target==1` then we fail to send a flow control update
(announced is never less than 1/2==0) and break our forward progress
guarantees.
b/259780449 internally.
This adds a small wait for all timers to finish executing on
WindowsEventEngine shutdown. I have seen this wait code triggered on
rare occasions where either 10's of tests are running concurrently, or
in an environment where IPv6 is detected but disabled, and connection
cancellation takes seconds to complete. I have not gotten to the bottom
of the latter problem, but feel WindowsEventEngine destruction can
tolerate some small extra time.

Earlier, we were simply using a 64 bit random number, but the spec
actually calls for UUIDv4.

Fix the end timestamp of `grpc.io/client/roundtrip_latency` to when we
receive the trailers from the previous end timestamp of when we clean-up
the call attempt.
The reason to do this is to make sure that `grpc.io/client/api_latency`
(the end-to-end latency for the call) is always greater than
`grpc.io/client/roundtrip_latency` and fix the bug found by
@stanley-cheung

This allows us to replace `absl::optional<TaskHandle>` with checks
against the invalid handle.
This PR also replaces the differently-named invalid handle instances
with a uniform way of accessing static invalid instances across all
handle types, which aids a bit in testing.
