Add LinkDriver interface and Driver package (#221) 
* Add attr validation

This commit removes unix.IFLA_UNSPEC and introduces checks for the interface name,
the link type and the queue disc fields.
Interface name validation is necessary to prevent an 'invalid argument' error
when creating a link with an empty name. Other checks were added to be consistent with the ip tools.

* Add network namespace type

This commit introduces the NetNS struct and integrates network namespace capabilities into link attributes.
This enhancement facilitates the creation of links, such as veth pairs, across different network namespaces
without the need to execute directly within those namespaces.

* Add LinkDriver interface

This commit introduces a Driver interface and changes Data and SlaveData fields within the LinkInfo struct
as LinkDriver to accommodate driver-specific data encoding, addressing the limitation
where LinkInfo.Data and SlaveData fields were merely byte slices without support for specific data encoding.

Drivers are registered globally with the RegisterDriver function.
For un-registered drivers, the default LinkData driver is used.

* Add Driver Package

This commit introduces the 'driver' package, which contains specific implementations of the LinkDriver interface.
It also includes the implementation of the Linux bond driver as LinkDriver and the bond slave driver as LinkSlaveDriver.

* Add Netkit and Veth drivers

This commit adds Netkit and Veth drivers.
