Summary: Created a new flag to allow reads from followers. Internally, we select a tserver using SelectTabletServerWithConsistentPrefix which selects the closest tserver in the same AZ. Test Plan: Ran a redis workload in a real cluster (AWS, 3 nodes, multi-AZ) With the flag set to false (default): Avg. latency with 2 reader threads: 0.84 ms With the flag set to true: Avg. latency with 2 reader threads: .17 ms Reviewers: karthik, mikhail, kannan, pritam.damania Reviewed By: pritam.damania Subscribers: amitanand, ybase Differential Revision: https://phabricator.dev.yugabyte.com/D4457

This commit fixes and extends the extension SQL scripts in a few ways, to allow upgrades from all the possible versions down where the origin is based on PostgreSQL 10, which is the oldest version supported by pg_hint_plan currently. PostgreSQL allows since v10 the maintenance of an extension using as base script the oldest version supported in combination of incremental scripts. A full set of upgrade scripts is added by this commit, considering v10 as the oldest path supported. As origin versions may have a partial schema created for the hint table with partial definitions, the correct rules are enforced for each version when it comes to extension dumps and GRANT rules. The schema for the hint table is only created in the base script. Regression tests are added to cover all these upgrade paths. DATA in the Makefile is changed to hardcode all the SQL scripts that need to be installed. Per pull request yugabyte#111 and issues yugabyte#110 and yugabyte#60. Backpatch-through: 10

Add a new tserver gflag.
When the flag is enabled for the tservers, it will allow the tserver's query layer to route a Redis read request to any tserver within the same DC/region/AZ even if that tserver is not the leader.
