updated the env var names from app controller to appset controller and also made them point to appset specific config instead of re-using app controller config.

+	command.Flags().BoolVar(&repoServerPlaintext, "repo-server-plaintext", env.ParseBoolFromEnv("ARGOCD_APPLICATIONSET_CONTROLLER_REPO_SERVER_PLAINTEXT", false), "Disable TLS on connections to repo server")
+	command.Flags().BoolVar(&repoServerStrictTLS, "repo-server-strict-tls", env.ParseBoolFromEnv("ARGOCD_APPLICATIONSET_CONTROLLER_REPO_SERVER_STRICT_TLS", false), "Whether to use strict validation of the TLS cert presented by the repo server")
+	command.Flags().IntVar(&repoServerTimeoutSeconds, "repo-server-timeout-seconds", env.ParseNumFromEnv("ARGOCD_APPLICATIONSET_CONTROLLER_REPO_SERVER_TIMEOUT_SECONDS", 60, 0, math.MaxInt64), "Repo server RPC call timeout seconds.")

set the default to 10 and max to 100 for now, let me know if that needs to be changed.

Chances this could be in 2.8 with the other repo server changes for caching?

I think we should add docs for ppl upgrading from 2.7 to 2.8 running without in-cluster TLS (this seems to have broken applicationset controller with error "transport: authentication handshake failed: tls: first record does not look like a TLS handshake" )

didn't see a notice about this cmd param config change here
https://argo-cd.readthedocs.io/en/stable/operator-manual/upgrading/2.7-2.8/

and missing from the sample in docs
