mod_smacks: Fix traceback on missing stanza counter This shouldn't be possible, yet it was.

mod_register_apps: Reduce yellow yelling in log message

mod_s2s_keepalive: Ignore errors from the local server If a stanza can't be delivered and instead an bounce is generated, the origin of the error, when different from the stanza 'from' should be indicated in the 'by' attribute of the <error>, which we look for here so this doesn't count as a successful ping. An error that does come from the remote means we have connectivity, but probably no XEP-0199 handling. This is fine. We care about connectivity, not protocol.

mod_s2s_keepalive: Fix identification of replies (error-replies included) Typo? This condition is supposed to filter out get and set (and anything else), not errors, which can still mean that there's connectivity, just no handling of XEP-0199.

mod_pubsub_alertmanager: Include status booleans in template input For easier conditionals, e.g. {firing&oh no} or {resolved&okay then}

mod_pubsub_alertmanager: Exclude "ends at" timestamp for unresolved alerts Wow, does the problem end in year 1? Let me get my time machine!

mod_pubsub_alertmanager: Add TODOs

mod_pubsub_alertmanager: Add some words about the node template

mod_pubsub_alertmanager: Minimal example of Prometheus and Alertmanager config

mod_pubsub_alertmanager: Add a README with initial docs
