component updater: persistent metadata.
Add a table to track cross-profile component usage. The table is a
protobuf that has entries recording component usage for each component
installed.
When a user signs in:
Component updater adds component usage entry when Load is called AND a
component is loaded(succeed or fail). Component updater deletes component
usage entry when Unload is called.
When no user signs in:
No entry is added or deleted.
BUG=chromium:811431
TEST=unittest
platform_AddPrinter.epson
e2e test: Load/Unload when multiple users sign in/sign out. Manually check
persistent metadata/component existence is corrrect after each operation.
TODO: have an autotest to cover the e2e test. crbug.com/839542
