[Offline Pages] Implement live page sharing.

Implement live page sharing:
- Adding a new temporary client namespace for the usage of live page
  sharing, which has a limit of one page per url and expiration period
  as one hour.
- Adding saveAndSharePage in OfflinePageUtils, implementing the workflow
  of save page, get page and share page.
