### Description Both doc's of master and 5.4 branches mention parameter that is missing from a code https://kamailio.org/docs/modules/5.4.x/modules/usrloc.html#usrloc.p.ka_logm...

3.56. ka_logmsg (str) The formatted log specification to be added to the message printed when the keepalive is received and roundtrip time is computed. The log message starts with "keepalive roundtrip: %u.%06u sec - ruid [%.*s]", then concatenates the value of this parameter and the end of line.

but seems it's missing in a code

``` [root@v0p1356-dispatcher kamailio]# kamailio -c 0(18199) ERROR: <core> [core/modparam.c:165]: set_mod_param_regex(): parameter <ka_logmsg> of type <1:string> not found in module <usrloc> 0(18199) CRITICAL: <core> [core/cfg.y:3592]: yyerror_at(): parse error in config file kamailio-my.cfg, line 73, column 69: Can't set module parameter ERROR: bad config file (1 errors) 0(18199) INFO: <core> [core/sctp_core.c:53]: sctp_core_destroy(): SCTP API not initialized [root@v0p1356-dispatcher kamailio]# ```

#### Reproduction

Add

`modparam("usrloc", "ka_logmsg", " to-uri: [$tu] remote-addr: [$sas]")`

to kamailio.cfg

#### Log Messages
