feat: Add devlink commands and RSS queues settings

[KTokarze]

This pull request introduces several new functionalities and exceptions for advanced network interface management, particularly focused on Linux systems and virtualization features. The changes add new methods for configuring SR-IOV, RSS queues, and MSI-X vectors, as well as new exceptions for more granular error handling. Documentation and tests have been updated accordingly.

New network interface configuration methods:

• Added set_sriov_drivers_autoprobe method to LinuxDriver, allowing enable/disable of SR-IOV driver autoprobe via sysfs.
• Added set_rss_queues_count and get_rss_queues_count methods to Linux RSS feature, enabling setting and retrieving RSS queue counts, including support for VFs via PCI address.
• Added set_msix_vectors_count and get_msix_vectors_count methods to Linux virtualization feature, supporting configuration and querying of MSI-X vectors by devlink or sysfs.
• Added reload_adapter_devlink method to Linux network interface for reloading adapters via devlink.
• Added get_vf_id_by_pci method to Linux virtualization feature to map a VF PCI address to its VF ID.

New exceptions for error handling:

• Introduced VirtualFunctionNotFoundException, HypervisorNotSupportedException, NetworkAdapterConfigurationException, and NetworkInterfaceNotSupported for more precise error reporting in network interface operations.

Documentation updates:

• Updated README.md to document all new methods, exceptions, and usage patterns for Linux network interface management, including SR-IOV, RSS, and MSI-X configuration. [1] [2] [3] [4] [5] [6]

Testing improvements:

• Added and extended unit tests for new SR-IOV driver autoprobe functionality in Linux driver feature. [1] [2] [3]

Supporting data structures and imports:

• Introduced MethodType dataclass for selecting method of MSI-X vector configuration (devlink/sysfs).
• Updated imports and logging setup for new features and exceptions. [1] [2] [3] [4] [5]

These changes provide more granular control and observability over network interface features, especially in virtualized and high-performance environments.
