- update sbroad submodule to commit
with support of UNION operator
- add integration tests for global
tables (sharded tables were tested
in cartridge tests)
- Usage:

`select a from t union select b from t2`

Currently only 2 cases are supported:
- config_file
- commandline_or_environment

Before this change we would silently replace an instance with current
grade not Online if a new instance with the same name wanted to join.
This was a mistake as it would allow a race condition when joining
several instances at once.

- update sbroad submodule to commit with support of to_char
- add some integration tests, note: there are also
integration tests in cartridge
- This function is implemented as calling `format` on
given datetime object
- Usage:

to_char(datetime, format)

select to_char(datetime_column, 'Last updated: %Y-%m-%d') from t

Second argument is optional and could be specified as `null`:

select to_char(datetime_column, null) from t

- format is specified with the same rules as in strftime function
