HttpStress: add randomized header operation

Aguments the stress suite with an "Echo Header" operation
which sends and receives a randomly generated set of headers.
Additionally expands random string to full alphanumeric or ascii range.
Fixes a bug where `n - 1` workers were being initialized.

Remove unnecessary use of volatile in PartitionerStatic (dotnet/corefx#39591)

`SharedInt`, which is just an object wrapper around a `volatile int` was being used even though a) the objects weren't actually being shared, and b) the stored `int` was sometimes being passed by `ref` and thus losing its voliatility in some cases anyway.

(It's not entirely clear why an object is being used, regardless, but from the comments it appears to be due to concerns around false sharing.  Presumably cases were found where the enumerators were all allocated up-front resulting in these ints stored as part of the enumerator objects ending up on the same cache line, so they were moved to objects allocated on discrete threads during MoveNext to minimize that possibility.)

Fold a bunch of CoreCLR's abandoned mutex tests into a parameterized test (dotnet/corefx#39050)

Fold a bunch of CoreCLR's abandoned mutex tests into a parameterized test

- There are a large number of tests in CoreCLR with a lot of redundancy, timing issues, and which take unnecessarily long to run
- Folded a bunch of them into the existing parameterized test and improved it to cover more cases to replace the tests in CoreCLR that will be removed
- Coverage is not 100% equivalent, but I belive this sufficiently covers the necessary aspects of the tests in CoreCLR that will be removed
