Issue being fixed or feature implemented

Previously before this PR, users submitting documents were expected to set the document created at and updated at time on the client side. Then Platform would validate in consensus that these values were close to to the current block time. This approach had a few downsides. First it meant that documents in mempool would expire even though users did nothing wrong. The second is that it required users to have a clock that was very close in time to the network time.

What was done?

Now created at and updated at are set by the block time. Meaning that they are automatic and users have nothing to set manually.

How Has This Been Tested?

Test suite is passing
