- Refactor so we can have more than one cas store for project store and cache.
- Refactor `UpstreamCacheClient` so it is not tied to a specific CidStore
- Refactor scrub to keep the GC interface ScrubStorage function separate from scrub accessor functions (renamed to Scrub).
- Refactor storage size to keep GC interface StorageSize function separate from size accessor functions (renamed to TotalSize)
- Refactor cache storage so `ZenCacheDiskLayer::CacheBucket` implements GcStorage interface rather than `ZenCacheNamespace`

* move openprocess cache to central location
* enable openprocesscache in projectstore so "getchunks" can send filehandles when requested

This change adds support for a namespace-qualified RPC endpoint for z$ at `/z$/<namespace>/$rpc` which may be used to validate RPC requests by URL inspection. The old scheme is still supported.

- Improvement: Add zenhttp-test and zenutil-test
- Improvement: Moved cachepolicy test to cachepolicy.cpp
- Improvement: Renamed cachestore tests from z$ to cachestore
- Improvement: Moved test linking so test for a lib is linked by <lib>-test
- Improvement: Removed HttpRequestParseRelativeUri in httpstructuredcache.cpp and use the one in cacherequests.h instead

* moved all RPC processing from HttpStructuredCacheService into separate CacheRpcHandler class in zenstore
* move package marshaling to zenutil. was previously in zenhttp/httpshared but it's useful in other contexts as well where we don't want to depend on zenhttp
* introduced UpstreamCacheClient, this provides a subset of functions on UpstreamCache and lives in zenstore

* ensure all access to m_Entries is done while holding lock
* RPC recorder concurrency fixes - setup/teardown of recorder needs to be done while holding an exclusive lock. Calls into recorder should be done while holding a shared lock.

this change aims to hide logging internals from client code, in order to make it easier to extend and take more control over the logging process in the future.
As a bonus side effect, the generated code is much tighter (net delta around 2.5% on the resulting executable which includes lots of thirdparty code) and should take less time to compile and link.
Client usage via macros is pretty much unchanged. The main exposure client code had to spdlog internals before was the use of custom loggers per subsystem, where it would be common to have `spdlog::logger` references to keep a reference to a logger within a class. This is now replaced by `zen::LoggerRef` which currently simply encapsulates an actual `spdlog::logger` instance, but this is intended to be an implementation detail which will change in the future.
The way the change works is that we now handle any formatting of log messages in the zencore logging subsystem instead of relying on `spdlog` to manage this. We use the `fmt` library to do the formatting which means the client usage is identical to using `spdlog`. The formatted message is then forwarded onto any sinks etc which are still implememted via `spdlog`.

- Feature: Add detailed stats on requests and data sizes on a per-bucket level, use parameter `cachestorestats=true` on the `/stats/z$` endpoint to enable
- Feature: Add detailed stats on requests and data sizes on cidstore, use parameter `cidstorestats=true` on the `/stats/z$` endpoint to enable
- Feature: Dashboard now accepts parameters in the URL which is passed on to the `/stats/z$` endpoint

This change separates out the disk and memory storage strategies into separate cpp/h files to improve maintainability.
