Summary:
On unexpected errors like missing blobstore keys the walker will now log the preceding node (source) and an interesting step to this node (not necessarily the immediately preceding, e.g. the affected changeset).
Validate mode produces route information with interesting tracking enabled, scrub currently does not to save time+memory. Blobstore errors in scrub mode can be reproduced in validate mode when the extra context from the graph route is needed.

Summary: Fix flaky test-walker-validate.t. There can be more than one route to the bad filenode, so wildcard the src and via fields when matching the output.

Summary:
Since Mononoke's filenodes were migrated to derived data framework
hg_linknode_populated alarm has been firing. The main reason was that there's
now a delay between hg changeset being generated and filenodes being generated.
This diff fixes it by making sure walker won't visit hg changesets without
generated filenodes (note that walker will visit these changesets later after filenodes will be
generated).
