It's pretty obsolete now but we can drop it later
if needed.

The new process-specific containers share a volume
under this path and they'll need to see the flag to
continue with the startup.

Initialization (the firstrun.sh script) is now run in it's own container.
The API/Messaging containers wait for the firstrun-container to
do it's thing.

The /opt/tak/data directory no longer exists
"by default" since the certs/logs volumes are no
longer there.

The firstrun.sh script copies the /opt/tak contents into the volume.
After that the services are started from under /mnt/tak.

…s TAK is hardcoded to use 127.0.0.1 to connect to Apache Ignite Cache.

* Set the new scripts exec permissions

… anything else

* Fixing port mapping

* The firstrun.sh is now idempotent
* Cert and Logs volumes return (for now?) and are properly symlinked
* Startup scripts now combined with if statement to select what process starts up
* Works locally (at least the WebUI opens on port 8080)

* Fix typo in start-tak.sh -script
* Update README
