This MR updates buildbox-run-bubblewrap's --help text to use the literal string "hardware-concurrency" rather than substituting in std::thread::hardware_concurrency() at runtime, as this means that the help text and man pages generated from it fail Debian reproducibility checks.

I implemented 3 optimizations in this MR to address the deployment issue of linker caching for large mono repo.

1. Add support to creation of multi-instances nested server. Currently, during creation of a nested server, a base instance from the parent server is always cloned and renamed to "" in the nested server. My changes allows one to preserve the instances names and clone a list of instances into the nested server. We need this particularly to create a nested server with one instance with remote cas and ac, and one instance without to avoid 400-500GB of linker output getting upstreamed while allowing compilation to benefits from the remote cas and ac.
2. Add support on the RECC's side to allow one to specify an instance for all linker command to use. This goes hand in hand with the above optimization to allow separation of linker traffic and compilation traffic to a different instance.
3. Add a RECC option to allow hash-offloading to be enabled only for linker command and disabled for compilation commands. This is needed as we have observed a serious timeout issue in hash-offloading in linker commands under high load. We have found that disabling hash-offloading from the compilation commands will alleviate this timeout issue as hash-offloading is quite a demanding offloading. We have also observed that at least with our build, enabling hash-offloading the compilation actually slow down the compilation cache hit my 3-5 times.
