rosbag::Bag.read_messages() does not provide return_connection_header parameter on kinetic branch

[ricber]

Hi,
I am launching this script (Ubuntu 16.04 - ROS Kinetic):

import rosbag

with rosbag.Bag('2019-05-24-09-53-28-high-density-imurenamed.bag', 'w') as outbag:
    for topic, msg, t, conn_header in rosbag.Bag('2019-05-24-09-53-28-high-density.bag').read_messages(return_connection_header=True):
        if topic == "/f746zg_imu/data_raw" or topic == "/f746zg_imu/mag":
            msg.header.frame_id = "nucleo_imu"
        outbag.write(topic, msg, t, connection_header=conn_header)

and I obtain the following error:

Traceback (most recent call last):
  File "rename_imu.py", line 4, in <module>
    for topic, msg, t, conn_header in rosbag.Bag('2019-05-24-09-53-28-high-density.bag').read_messages(return_connection_header=True):
TypeError: read_messages() got an unexpected keyword argument 'return_connection_header'

The "return_connection_header" parameter is not available in the kinetic branch. Why this? In my case, if I don't copy the connection header, the /tf_static topic will not be published in the new bag.

The feature was added in #1372 for Melodic and in general features are not backported to older ROS distro. Therefore I am closing this ticket.
