This patch set implements two ideas improve ovsdb connection scaling:
* Allow multiple jsonrpc connection to share a single ovsdb monitor, thus
maintaining a single set of changes.
* With in the same monitor, cache the json object generated for an update.
If the same update is requested by another jsonrpc connection, the
cached json object can be used, avoid regenerating it from scratch.

I don't yet have any useful data on speed improvements from both changes.
The plan is to to collect them and report back in the next few days.
If we don't want to apply them without the performance data, then
please consider this posting as RFC.
