Add Session wrapper
With this patch we can now use gocqlx like:
```
session.Query(`SELECT * FROM struct_table`, nil).Get(&v)
```
instead of (old format):
```
gocqlx.Query(session.Query(`SELECT * FROM struct_table`), nil).Get(&v)
```

This patch adds the power of GocqlX to UDTs.
Now you can make a struct be UDT compatible by adding a single line.
```
type FullName struct {
gocqlx.UDT
FirstName string
LastName string
}
```

We have a structure type that implements UnmarshalCQL method.
We use it to unmarshal a user defined type. We also want to use the same struct for scanning an entire row.
There is StructScan method available in gocqlx for this purpose when iterating over rows, but no equivalent when doing a Select.
This commit introduces the possibility when doing select/get as well.

We used to rely upon NumRows to determine if there are
new pages available. This is not correct since the server
is allowed to return empty pages with has_more_data flag
set and the needed data to do this is not exposed by
the gocql driver.
We simply remove these checks and let the driver decide
when to stop reading.
