Control distribution order on dbroot / segment level

Usual the distribution of storing data is not under control of the user.

Data will be loaded in the order of loading.
The only possiblitiy to control a bit, is to use mode 2 or 3 with cpimport for a certain PM.

Sometimes it can make sense to have control over the distribution process.

Similar to
-P List of PMs ex: -P 1,2,3. Default is all PMs.

-D  List if DBroot ex -D 1,2,3 Default is all DBroots. If a certain PM is not defined, PM1 will be  used.

-S List of Segments ex -S 1,2,3 Default is all Segments. If a certain PM is not defined, PM1 will be  used.

The same options should be possible for the bulk API
createBulkInsert(const std::string &db, const
std::string &table,
uint8_t
mode, uint16_t pm)

Add uint16_t dbroot  and uint16_t segment

createBulkInsert(const std::string &db, const

std::string &table,

uint8_t

mode, uint16_t pm, uint16_t dbroot, uint_16_t segment)

dbroot = 0 no preference. Otherwise the only the handed over dbroot will be filled.
If pm = 0, PM1 will be choosen.

segment = 0 no preference. Otherwise the only the handed over segment will be filled.
If pm = 0, PM1 will be choosen.

If batch data is greater then free space in specified available, the next in number will be taken.
