Re: [sr-dev] [kamailio/kamailio] dialog: add dialog init, start end end timestamps to the output of dl… (#2279)

Thanks! It can be merged.

However, for better flexibility, I was thinking to add an option parameter to this command to specify the fields to be returned in a string-of-char-flags manner. Have hash label, hash id and call-id always int attributes of the output, the the rest be specified in the parameter, like:

* `f` - from uri * `F` - from tag * `t` - to uri * `T` - to tag * ...

Then use `kamcli rpc dialog.briefing "fFtT..."` -- the order of char-flags won't matter. When the parameter is not provided, a default value can be used for it (like what is printed now, before or after this PR).
