The vault instances lose the raft leader status, while loading the `vault-auth-tee` plugin, because the gramine enviroment slows down the `execve` significantly. Using `performance_multiplier` relaxes the timeouts for the raft protocol. see also: hashicorp/vault#28009 Signed-off-by: Harald Hoyer <[email protected]>

I have one plugin, which is taking a while to start (on the os execve level). This seems to make the raft leader inresponsive and it loses its leadership. With the newly elected leader trying to start the plugin, the game starts from the beginning.
Workarounds included tweaking:
But this really slows down everything raft related.
Anyway, it would be nice, if the raft leadership won't get lost by slow plugin loading...
