infinitepush: delete infinitepushcommands.py and related tests

This patch drops infinitepushcommands.py and the tests which were related to the
command `debugfillinfinitepushmetadata` introduced in the commit.

The patch also drops a config option which was related to
debuginfinitepushmetadata command.
