Add some notes about updating across mongodb version to unifi pkg/README.

Remove the notes about kern.maxthreads now that the OS defaults have been
raised.

+Migrating between MongoDB versions
+----------------------------------
+Unifi uses MongoDB to store its database. Databases can only be updated
+directly across one major MongoDB version (3.4->3.6, 3.6->4.0, 4.0->4.2,
+4.2->4.4).
+
+If you need to update MongoDB across a larger gap, the simplest way to
+move Unifi data across is to make sure you have an up-to-date Unifi .unf
+backup (check /usr/local/share/unifi/data/backup and maybe trigger one
+from the web interface). Then stop Unifi and move the old MongoDB
+database out of the way (the directory /usr/local/share/unifi/data/db),
+restart Unifi and open the web interface; it will create a new database
+and allow restoring from a backup file.
+
+Alternatively "mongodump" (in the mongo-tools package) can be used.
+You probably won't need it, but here are some instructions that worked
+for the port maintainer and may be useful.
+
+Backup with the old mongodb version installed and unifi running -
+
+$ mkdir unifi-backup; cd unifi-backup
+$ mongodump --port=27117
+$ doas rcctl stop unifi
+$ doas cp -rp /usr/local/share/unifi /usr/local/share/unifi.backup

+Then after installing the newer mongodb you can restore - the steps
+below increase the number of file handles from the default to avoid
+problems.
