This defines a 'context' object that is passed to each API handler.
Right now the context just has a unique 'requestID' for each API call.
The next steps would be:
- use this 'requestID' in our logging.
- determine the best way to format the logging to include this info.
In particular for log events that generate multiple entries in the log
we can use the requestID to help correlate the log entries.
Adding the requestID to the logging will be a challenge since it could mean
changing every single logrus.XXX() call to pass in the 'context' object.
But first step is to agree on a format, which we can discus in a subsequent
PR, but my initial thoughts are to add it right after the timestamp:
current format:
INFO[0039] POST /v1.21/build?buildargs=%7B%22foo%22%3A%22xxx%22%7D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&memory=0&memswap=0&rm=1&t=&ulimits=null
proposed format:
INFO[0039-83dea1222191] POST /v1.21/build?buildargs=%7B%22foo%22%3A%22xxx%22%7D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&memory=0&memswap=0&rm=1&t=&ulimits=null

This file was not well documented and had very high cyclomatic complexity.
This patch completely rearranges this file and the ImageDelete method to
be easier to follow and more maintainable in the future.
