Subject: [PATCH] sql: add another way to change SQL default engine
Currently, the pragma sql_default_engine is used in the *.test.sql
tests to change the default SQL engine. But in the issue
tarantool/tarantool#4511, this pragma will be removed. To avoid
failures in these tests because of this, in addition to the
current one, another way to change this parameter was implemented.

"engine" value has a special meaning for *.test.sql files: if it is "memtx" or
-"vinyl", then the corresponding engine will be set using "pragma
-sql_default_engine='memtx|vinyl'" command before executing commands from a test
-file.
