This adds an example clone and deploy step that allows you to modify
each top level repository before pulling in the rest of the example's
dependencies. This allows us to not pull in a copy of mbed-os for each
example in CI and instead symbolic link the already cloned copy, saving
valuable time and disk space
Adding the new compile option allows the marking of a set of examples to
indicate whether they should be compiled or not. For the update process
examples that are not compiled will not be auto updated irrespective of
that setting.
Other changes to make return logic from some functions in update.py more
efficient and some typos in the lib file.
Changes:
Refactor examples.py to add a new command line option to provide an update
tag.
Refactor examples.py to add new functionality to update the version of
mbed-os in the examples to a supplied tag.
Refactor examples.py to make cloning the example repos, updating their
mbed-os version and compiling, into library functions and move to a new
library module.
Refactor the format of the examples.json file to make it compatible with
both examples.py and update.py.
Refactor update.py so that examples are test compiled prior to updating.
Refactor update.py so that only examples tagged as auto-updatable and that
fully compile are automatically updated.
