 Currently we run 7 round-the-clock instances of proxy-go:
 1. snowflake-proxy-restartless
 1. snowflake-proxy-17h
 1. snowflake-proxy-23h
 1. snowflake-proxy-29h
 1. snowflake-proxy-standalone-17h
 1. snowflake-proxy-standalone-23h
 1. snowflake-proxy-standalone-29h

 snowflake-proxy-restartless is an experiment for #25688, so put it aside.
 Of the remaining 6, the only difference is what broker they correspond
 with:
 * 3 for !https://snowflake-reg.appspot.com/ (the old App Engine–bound
 broker)
 * 3 for !https://snowflake-broker.bamsoftware.com/ (the current standalone
 broker)

 We fully switched away from the App Engine broker
 [[comment:9:ticket:22874|10 months ago]]. Nothing in the source code
 refers to snowflake-reg.appspot.com any longer. So I propose we stop
 running the 3 instances that use the old App Engine broker:
  * snowflake-proxy-17h
  * snowflake-proxy-23h
  * snowflake-proxy-29h
