Spec clarification required - Flags.ReportFullState

[RassK]

What

ReportFullState is used to recover missing data. As seen some interesting implementations already, I would like to clarify the spec a bit more.

• Does agent needs to keep track what it ALREADY sent?
• Does agent needs to send everything that it knows (and didn't send / generate yet) limited by matching capabilities.

Current description for the reference:

ReportFullState flag can be used by the Server if the Client did not include
some sub-message in the last AgentToServer message (which is an allowed
optimization) but the Server detects that it does not have it (e.g. was
restarted and lost state). The detection happens using
AgentToServer.sequence_num values.
The Server asks the Agent to report the full status again by sending
a new, full AgentToServer message.
