Adds support for creation of the sharded memtx spaces via pico.sql().

The reason of this refactoring is that we need Picodata specific
API rather then the API provided by tarantool module. For example,
table creation needs access to the clusterwide API for sharded and
global spaces.

Closes #321

INSERT command in the SQL library (sbroad) was refactored. Now
we don't need a custom SQL function to calculate bucket ids. So,
remove redundant functions from picodata SQL module.

Also fix some rustdoc warnings

The following commands are affected:

- `picodata connect [user@][host][:port]`
- `picodata run --peer`
- `picodata run --listen`
- `picodata run --http-listen`
- `picodata run --advertise`
- `picodata expel --peer`

Only `picodata connect` respects the username. Other options just ignore
it.

- Provide new `struct Address`
- Replace `try_parse_address` function with `impl FromStr for Address`.
- Provide both unit and pytests
