This commit introduces:
 * statement and portal storages;
 * statements with parameter oids;
 * portal encoding;
 * interactive portals;

Portal encoding defines in which format (binary or text) columns
are returned.

Interactive portals allow to limit the number of rows returned from
execute method. Other rows can be extracted by calling execute again
on the same portal.

- add new ddl opcode for renaming procedure
- update sbroad submodule to get sql support
- syntax:

alter procedure "foo" rename to "bar" option(timeout=3)
alter procedure "foo"(int, int) rename to "bar"

Current commit introduces
- _pico_routine replicated table
- procedure creation with SQL API

This patch adds initiator field to most of the events. Initiator is
added to members of Op enum which do not contain it already (e g owner
in CreateUser serves as initiator). To me it is reasonable to remove
as_user from CaS/ACL checks because it matches initiator. But I decided
not to do this just yet.

Additionally I've mande small cleanup to UserMetadata to avoid need for
intermediate step in decoding when we first fetch tuple and then decode
it into model struct.

At the later stage I discovered that sbroad applies the same validation
rules during parsing of grant/revoke statements and even its own
Privilege enum that is a ~copy of our PrivilegeType. Unfortunately
at the moment there is no way to share code between picodata and sbroad
efficiently (now only tarantool-module is shared and it is not suitable
for such kind of things) so it still makes sense to have this in
picodata because this is the point where all APIs converge to the single
point (CaS). In the future all other ways of validation should be
removed. Aside from sbroad similar kind of validation is performed
independently on lua API side.

Note that in prior commit 45ba7392 we've
removed all privileges from role super. This patch removes privileges
from admin that do not match the model: namely all privileges on
universe except session and usage. With this patch it is no longer possible
to grant or revoke such privileges.

This allows future constructors to enforce invariants.
Additionally this commit removes redundant set_schema_version on Op by
passing schema version to corresponding Op constructors.

This patch reintroduces instance-related events (e.g. `join_instance`)
which were accidentally disabled in a bugfix of the DML handler (see
commit 52ed9237 for more information) due to the lack of tests.

Furthermore, this patch adds the following events:

* expel_instance
* change_config, which tracks changes in `_pico_property`

This was the original intended change of the patch, but the apparent
breakage of the preexisting events called for action.

This change allows for creators of corresponding objects to consequently have all privileges on them.

Rename space object type to table

Now the records look like this:

```
{
  "message": "instance is starting",
  "severity": "low",
  "time": "2023-11-22T22:10:24.211+0300",
  "title": "local_startup"
}
{
  "message": "target grade of instance `i1` changed to Online(7)",
  "severity": "low",
  "time": "2023-11-22T22:10:24.334+0300",
  "title": "change_target_grade"
}
{
  "message": "current grade of instance `i1` changed to Replicated(7)",
  "severity": "medium",
  "time": "2023-11-22T22:10:24.436+0300",
  "title": "change_current_grade"
}
```

sbroad needs to be updated to the version that supports newer
tarantool-module

sbroad support for new module version was merged here:
https://git.picodata.io/picodata/picodata/sbroad/-/merge_requests/355

- Now we explicitly store the current & target vshard configuration in
  global storage
