What does this PR do?

  1. Uses hickory dns for reqwest based networking.
  2. Temporarily gates it behind an environment variable to allow runtimes to test and opt-in.

Motivation

https://github.com/DataDog/dd-source/pull/355564

The default DNS resolver used when reqwest does not have the hickory-dns feature has a few issues:

It uses tokio::spawn_blocking for each DNS resolution, because it uses the system getaddrinfo that is sync. This can contribute to saturating the tokio blocking pool in case of slowness
It seems it does this for all DNS requests and has no applicative cache. For df-executor, it results in about 6000 DNS requests per second, the vast majority of them being DNS resolution to S3 and GCP Blob Store.
Hickory DNS is async and has applicative DNS record caching, compliant with DNS TTLs, allowing to:

Avoid saturating the blocking pool (no more blocking tasks for df-executor's IO pool with this PR deployed in staging)
Avoid DNS flooding (signal is noisy for now, I'll take a second look at a larger scale after a full night running)

The non-use of the blocking pool is particularly nice, since it lets us avoid the uncontrolled thread that can break things on forks.

Additional Notes

   ├ In the unique reclaim path of `BytesMut::reserve`, the condition
     ```rs
     if v_capacity >= new_cap + offset
     ```
     uses an unchecked addition. When `new_cap + offset` overflows `usize` in release builds, this condition may incorrectly pass, causing `self.cap` to be set to a value that exceeds the actual allocated capacity. Subsequent APIs such as `spare_capacity_mut()` then trust this corrupted `cap` value and may create out-of-bounds slices, leading to UB.
     
     This behavior is observable in release builds (integer overflow wraps), whereas debug builds panic due to overflow checks.
     
     ## PoC
     
     ```rs
     use bytes::*;
     
     fn main() {
         let mut a = BytesMut::from(&b"hello world"[..]);
         let mut b = a.split_off(5);
     
         // Ensure b becomes the unique owner of the backing storage
         drop(a);
     
         // Trigger overflow in new_cap + offset inside reserve
         b.reserve(usize::MAX - 6);
     
         // This call relies on the corrupted cap and may cause UB & HBO
         b.put_u8(b'h');
     }
     ```
     
     # Workarounds
     
     Users of `BytesMut::reserve` are only affected if integer overflow checks are configured to wrap. When integer overflow is configured to panic, this issue does not apply.
