Allow setting `shard_count` for a `resmoke_suite_test` beyond the arbitrary limit of 50 typically enforced by Bazel. A config transition of `--test_sharding_strategy=forced=N` is applied when set above 50.

Updates the bazel wrapper so that any `--test_sharding_strategy` passed via CLI disables the config transition and respects the user-provided strategy.

Updates a couple scripts that process the bazel output directory to account for artifacts being found under the different configuration transition outputs.
