[PATCH cluster/docs/manager v2 0/8] add warning messages for high token timeouts in clusters

["Michael Köppl" <m.koeppl@proxmox.com>]

This patch series introduces warnings informing users about high token
timeouts in their clusters. A recent change [0] lowered the token
coefficient for clusters and allowed adapting it. However, this change
only affects new clusters. As described in [1], users with existing
cluster should be informed about the high token timeouts in their
configurations and what they can do to alleviate this problem.

Thus, warnings are added to the `pvecm status` command as well as to the
cluster join info dialog in the web UI. The warning in the web UI warns
users about the effect adding another node would have to allow them to
make an informed change before adding another node.

changes since v1 (thanks to @Friedrich for the feedback on v1):
- add pve-docs patch to allow using get_help_link to directly link to
  an anchor in the local documentation (then used to link to the section
  on changing the token coefficient)
- add pve-docs patch to define explicit anchor for the "Changing the
  Token Coefficient" section
- add pve-docs patch extending the section for Changing the Token
  Coefficient slightly, informing users of the potential warning
  messages in the pvecm status output
- change the threshold for "strongly recommend" from 50s to 45s as
  suggested by @Friedrich
- adapted the name of calculate_total_timeout to
  calculate_membership_recovery_timeout
- adapted commit messages for preparatory pve-manager patch (no
  functional changes intended)
- moved the warning message in pvecm from `pvecm nodes` to `pvecm status`
- replaced the URL in the pvecm warning message with a reference to the
  pvecm man pages
- link to local documentation in ClusterEdit.js
