Subject: [PATCH] upgrade: fix generated sequence upgrade from 2.1

The bug was in an attempt to update a record in _space_sequence
in-place, to add field path and number. This was not properly
supported by the system space's trigger, and was banned in the
previous patch of this series.

But delete + tuple update + insert work fine. The patch uses them.

To test it the old disabled and heavily outdated
xlog/upgrade.test.lua was replaced with a smaller analogue, which
is supposed to be created separately for each upgrade bug.
According to the new policy of creating test files.

The patch tries to make it easy to add new upgrade tests and
snapshots. A new test should consist of fill.lua script to
populate spaces, snapshot, needed xlogs, and a .test.lua file.
Fill script and binaries should be in the same folder as test file
name, which is located in version folder. Like this:

 xlog/
 |
 + <test_name>.test.lua
 |
 +- upgrade/
    |
    +- <version>/
    |   |
    |   +-<test_name>/
    |     |
    |     +- fill.lua
    |     +- *.snap
    |     +- *.xlog

Version is supposed to say explicitly what a version files in
there have.

Closes #4771

(cherry picked from commit 6d45a41e762ac13826604c3a5690a8800f62960a)

+## How to add a new upgrade test
+
+Firstly, for a new test should be prepared a `fill.lua` file. Here
+should be code to populate needed spaces, create xlogs, snapshots.
+
+`Fill.lua` should be run in an old Tarantool version, upgrade from
+which is going to be tested. This will produce `.xlog` and `.snap`
+files. They should be saved into
+`xlog/upgrade/<version>/<test_name>/` folder. Snapshot is usually
+enough. Version is the old Tarantool version. Test name is a name
+of test file, which will test recovery from these xlogs. It should
+obey to the same rules as other test file names.
+
+Secondly, it is necessary to add a `<test_name>.test.lua` file to
+`xlog/` folder, to all the other tests. It should start a new
+instance of Tarantool with workdir set to
+`xlog/upgrade/<version>/<test_name>/`. Then this file should
+ensure, that `box.upgrade()` works fine, and all data is recovered
+correctly.
+
+The following directory structure should be in the result:
+```
+ xlog/
+ |
+ +- <test_name>.test.lua
+ |
+ +- upgrade/
+    |
+    +- <version>/
+        |
+        +- <test_name>/
+           |
+           +- fill.lua
+           +- *.snap
+           +- *.xlog
+```
