Associate Coin snapshot builds with Coin integration IDs

This change adds a new setup.py option called --package-timestamp
which allows setting the "dev" part of the version number of a
snapshot package.

It also modifies coin_build_instructions.py to set the package
timestamp to the value of the Coin integration ID.

This has a couple of benefits:
1) We can look up the build and test logs of a specific package
on testresults.qt.io.
This can also be looked up for non-snapshot builds, the
"timestamp = Coin integration ID" can also be found in the
generated __init__.py file.

2) All the different platform packages within one integration
will have the same timestamp, which allows pinning snapshot
packages inside a pipenv Pipfile.

3) It's easier to figure out which packages were built as part
of the same Coin integration.
