[tarantool-patches] [PATCH] recovery: build secondary index in hot standby mode

[Ilya Kosarev <i.kosarev@tarantool.org>]

Secondary index was being built after reading xlog
except for the force recovery case,
when it was being built immediately after reading snapshot.
Now it is also being built immediately after reading snapshot
in case of hot standby mode in order to be ready by the time
original instance quits.

Closes #4135
