[fix](readconsistency) avoid table not exist error (#37593) (#37641)
Query following createting table would throw table not exist error.
For example.
t1: client issue create table to master fe
t2: client issue query sql to observer fe, the query would fail due to
not exist table in plan phase.
t3: observer fe receive editlog creating the table from the master fe
After the pr:
query at t2 would wait until latest edit log is received from master fe
in the observer fe.
pick #37593
