Removed 'test_run:' prefix. It is convenient to determine a repository
in tarantool-patches mailing list, but have no much sense in the commit
itself (because it is already in test-run repository).

I suggest to use '--subject-prefix' option for 'git format-patch' when
preparing changes for a repository other then tarantool.

Expanded the description a bit:

 | The option can be used when it is not possible to grab 'box.cfg.log'
 | value from a tarantool instance: say, when the instance is stopped or
 | crashed.


> Usage: grep_log(self, node, waht, bytes, {filename = XXX})

Fixed typo: waht.

I rewrote it a bit to avoid confusion with self / colon and so:

 | Usage:
 |
 |  | local test_run = require('test_run').new()
 |  | test_run:grep_log(node, what, bytes, {filename = <...>})

> Search custom log grep_log(self, node, waht, bytes, {filename = XXX})

Removed the changelog entry from the commit message. It should be in a
email (at least for tarantool), but should not be part of a commit
message.
