Set the number of resources available to Bazel. Takes in an assignment to a float or HOST_RAM/HOST_CPUS, optionally followed by [-|*]<float> (eg. memory=HOST_RAM*.5 to use half the available RAM). Can be used multiple times to specify multiple types of resources. Bazel will limit concurrently running actions based on the available resources and the resources required. Tests can declare the amount of resources they need by using a tag of the "resources:<resource name>:<amount>" format. Overrides resources specified by --local_{cpu|ram|extra}_resources.
