feat: consider using Sentry uptime monitoring

[mcdurdin]

Sentry now offers uptime monitoring for websites for $1/month. Consider doing this for api.keyman.com, keyman.com, help.keyman.com, s.keyman.com, downloads.keyman.com, keymanweb.com, blog.keyman.com?

What would that give us compared to http://keyman.status.languagetechnology.org/?

Good question -- primary thing is probably clearer status messages. The notification emails from nodeping are pretty obtuse and take a fair bit of parsing to be clear.

We can improve the nodeping notifications to support escalation also. That would help.
