Introduce getter for asio::connection in asio::dbus_interface

[jbbjarnason]

Before I go through the process of making a PR on gerrit.

Do you have something against populating a getter for the shared_ptr of asio::connection within asio::dbus_interface?

By the getter, do you mean something like https://gerrit.openbmc.org/c/openbmc/sdbusplus/+/64536?

@mine260309 Nope, even more simple, here is what I mean:

@williamspatrick is this something you would consider merging? can be very handy if you are writing a component to minimize the parameter count. Also sort of follows asio convention of getting a io_context. See this for reference https://live.boost.org/doc/libs/1_84_0/doc/html/boost_asio/reference/basic_stream_socket/get_executor.html

If so I can create a patch, get a CLA signed and submit to gerrit.

@omarhogni - Sure.
