/*
this function allows overriding any string-valued config option with
a sensible-named environment variable
e.g. `MK_CONFIG_MEILISEARCH_APIKEY` sets `config.meilisearch.apikey`
you can also override a single `dbSlave` value,
e.g. `MK_CONFIG_DBSLAVES_1_PASS` sets the password for the 2nd
database replica (the first one would be
`MK_CONFIG_DBSLAVES_0_PASS`); in this case, `config.dbSlaves` must
be set to an array of the right size already in the file
values can be read from files, too: setting `MK_DB_PASS_FILE` to
`/some/file` would set the main database password to the contents of
`/some/file` (trimmed of whitespaces)
