Mysql config file utf8.cnf has become dumping ground

[si-the-pie]

The utf8.conf file is setup by

cyclestreets-setup/utility/installBaseWebserver.sh

Line 213 in 1c2deae

mysqlUtf8CnfFile=/etc/mysql/conf.d/utf8.cnf

it was originally created to ensure default-character-set=utf8mb4 but has also become a bit of a dumping ground for other settings.

This needs reviewing, renaming and tidying.

It should be renamed to cyclestreets.cnf for a start.

Ideally we should avoid needing to modify it at all, unless essential. MySQL installations use UTF-8 [mb4] by default now (rather than Swedish, in the MySQL4 era), so at least that aspect shouldn't be necessary.
