teragrep syslog stream config/props do not work

[eemhu]

Describe the bug

The "dpl.pth_10.transform.teragrep.syslog.parameter.host"; "dpl.pth_10.transform.teragrep.syslog.parameter.port"; "dpl.pth_10.transform.teragrep.syslog.restrictedMode"; props do not work, because the code does not use the variables, instead it declares new ones overriding the global variables. Probably happened in refactoring

Expected behavior

should work

How to reproduce

try changing props and then try with command parameters instead. Props do not work, but parameters in the command will.
