8653: Bug fix: replication fails when a branch is deleted and tag with same name is created

Our logic to update refs in a read replica was tracking updated refs by path, so when branch b1 was deleted and tag b1 was added, the code was mixing them up and trying to update the branch with the tag ref.

The fix is to track replicated refs by ID, instead of by path, to avoid collisions. This also changes the first return parameter of the pullBranches function, but none of the three places that call this function assign that first return param to a variable, so that change doesn't affect anything.
8643: Support for schema names in table renames

Also support for changes in enginetest harness setup in GMS

2784: implement EXPLAIN and EXPLAIN PLAN

Moving our current implementation of EXPLAIN to EXPLAIN PLAN, and replace EXPLAIN with a dummy implementation of MySQL's EXPLAIN

Looks like this now:
tmp2/main> explain select * from t;
+----+-------------+-------+------------+------+---------------+------+---------+------+------+----------+-------+
| id | select_type | table | partitions | type | possible_keys | key  | key_len | ref  | rows | filtered | Extra |
+----+-------------+-------+------------+------+---------------+------+---------+------+------+----------+-------+
| 1  | SELECT      | NULL  | NULL       | NULL | NULL          | NULL | NULL    | NULL | NULL | NULL     |       |
+----+-------------+-------+------------+------+---------------+------+---------+------+------+----------+-------+
1 row in set (0.00 sec)
tmp2/main> explain plan select * from t;
+------------------+
| plan             |
