identify(Traits) not found

[julioromano]

Describe the bug
I can't find the identify(Traits) api in analytics-kotlin even though the docstring of all the identify APIs clearly state:

Traits and userId will be automatically cached and available on future sessions for the
     * same user. To update a trait on the server, call identify with the same user id.
     * You can also use {@link #identify(Traits)} for this purpose.

hey @julioromano , thanks for reporting this issue. this is a disparity with the swift api. we'll add this api.
