T1733: Store credentials in Vault
Commits
rVIPER1c6f3be2ef97: Fetch credentials from Vault
Summary

Connect to Vault. Allow to fetch a credential and login again if the token
is expired, as the current duration lease is 4 hours.

vendor/vault.tcl is a work-in-progress Vault client implementation in TCL,
to be integrated in a future tcllib revision. Once released, that file will
be removed from the repository to use directly the tcllib one.

Allow nickserv, MySQL and RabbitMQ to consume secrets. The first two are
handled by configuration, the RabbitMQ one by this change.

Ref T1733.

Test Plan

Tested live on Daeghrefn and with a full restart on Wearg.

By coherence with TCL commands and our own commands (e.g. registry), I'd suggest to add a procedure vault to dispatch vault subcommand to vault_get, vault_login, etc. if they exists.

That worked at some point, probably when this was the last instruction,
but now it can't be the default return value if it's followed by another line (return $credential).

And indeed:

Does that package provides ::json::write?
