# Creates a new Anywhere Cache for a specified bucket and waits for it
# to become active.

# This method initiates the creation of an Anywhere Cache in the given zone for
# the specified bucket. After sending the creation request, it polls the status
# of the cache with an exponential backoff strategy until the cache's state is
# "running". Progress and final status are printed to the console.
