How does one find out which application is associated with an indicator icon?
The Application Indicator Service has an internal API that will allow grabbing a list of all the indicators, which includes their DBus addresses. You can do that using this command line:
gdbus call --session --dest com.canonical.indicator.application --object-path /com/canonical/indicator/application/service --method com.canonical.indicator.application.service.GetApplications
You'll get back something not super useful, as it's in a psuedo-JSON format. If you write a script you can pull it into a parser and work with it. If you're curious about doing it just once, just read through the text. You're looking for a field that is like this: :1.XXX That is the DBus address for the indicator.
Once you have the address for the indicator you can ask DBus what the PID is for that indicator. You request the PID of :1.123 like this:
gdbus call --session --dest org.freedesktop.DBus --object-path / --method org.freedesktop.DBus.GetConnectionUnixProcessID :1.123
After you now have the PID you can ask /proc for information on the process. For example if you wanted to know the command use to launch process number 1 you could do:
cat /proc/1/cmndline
Good luck!

Unfortunately -
gdbus call --session --dest com.canonical.indicator.application \
--object-path /com/canonical/indicator/application/service \
--method com.canonical.indicator.application.service.GetApplications
does not exhaustively enumerate all indicator icons or their sub-indicators. The MI (messaging indicator) menu interfaces with several sub-indicator communication aps. are not listed. Also missing are the power, volume and clock indicator info.
qdbus is simpler to use and d-feet provides a GUI to do the same, as well as easily list property values.
Use qdbus as follows:
qdbus --literal | sort
triple click to select com.canonical.indicator.application w/ nl in the output
...
:1.97
:1.98
ca.desrt.dconf
com.canonical.AppMenu.Registrar
com.canonical.hud
com.canonical.indicator.application
com.canonical.indicator.datetime
com.canonical.indicator.messages
com.canonical.indicator.printers
com.canonical.indicator.session
com.canonical.indicator.sound
com.canonical.Unity
...
Compose the next command with the bash history uparrow repeat command (delete the | sort to leave just qdbus --literal) and press the middle mouse button to complete the command:
qdbus --literal com.canonical.indicator.application
Triple click the last line
/
/org
/org/ayatana
/org/ayatana/indicator
/org/ayatana/indicator/service
/com
/com/canonical
/com/canonical/indicator
/com/canonical/indicator/application
/com/canonical/indicator/application/service
Press the repeat history uparrow, space bar and the middle mouse button to compose:
qdbus --literal com.canonical.indicator.application /com/canonical/indicator/application/service
Double click to select the desired method in the output and press uparrow, space bar and middle mouse button to create the command and press enter to run it. (\ line continuation is added for clarity in this example):
qdbus --literal com.canonical.indicator.application \
/com/canonical/indicator/application/service \
com.canonical.indicator.application.service.GetApplications
This outputs only the BT and NM indicator info (pretty printed here for exposition)

The other indicators are referenced as the other com.canonical.indicator. ... interfaces (listed at the start), however this is probably the must utile but sub-menu indicator aps are still unidentified:
qdbus --literal com.canonical.AppMenu.Registrar \
/com/canonical/Unity/Panel/Service \
com.canonical.Unity.Panel.Service.Sync
