David Ostrovsky b6d34da66a RFC Bazel: Fallback to sandboxed spawn strategy if remote not supported
Fallback to sandboxed spawn strategy if remote spawn strategy is not
supported, as suggested in [1]:

If you currently use remote execution with --strategy=remote and/or
--spawn_strategy=remote and have actions that might not be executed
remotely, consider removing those strategy flags completely, in this
case bazel will pickup the first available strategy from the default
list, which is remote,worker,sandboxed,local. Alternatively, add a
strategy to fallback to if remote is not possible for an action, for
example --spawn_strategy=remote,sandboxed will fallback to a sandboxed
execution if remote is not possible.
