Fixed the following warnings:
dra_test.go:884:2: singleCaseSwitch: should rewrite switch statement to if statement (gocritic)
	switch podName {
	^
dra_test.go:686:4: SA4006: this value of kubeletPlugin is never used (staticcheck)
	kubeletPlugin = newDRAService(ctx, f.ClientSet, nodeName, driverName)
        ^

Unix socket path has to be <= 108 characters in length on Windows.
Shortened DRA socket path for TestConnectionHandling and
TestRegistrationHandler tests should fix the test run on Windows.

Added an ability to specify the socket path for the DRA gRPC
service in the e2e node tests.

The PluginSocket option is added to allow setting the name
of the socket inside the directory where the DRA driver
creates the socket for the DRA gRPC calls. This is used by
the kubelet to connect to the DRA plugin.

The newDRAService and newRegistrar functions are updated to
accept a socketPath parameter, which is used to configure
the PluginDataDirectoryPath and PluginSocket options for the
DRA plugin.

This change enables more flexible configuration of the DRA
plugin in e2e tests, allowing for testing with different
socket paths.

Added tests to verify DRA functionality with 2 different socket
configurations:
- the same socket is used for the registration and the DRA service
- 2 separate sockets are used for the registration and the DRA service

Used table-driven ginkgo to avoid code duplication:
specs https://onsi.github.io/ginkgo/#table-driven-tests

This change enhances the robustness of the DRA e2e tests by
validating its behavior with different socket setups.

Fixed race condition caused by removing already removed
socket directory.

Using the same socket path for different test cases caused
test failure on windows:
listen unix C:\Users\azureuser\AppData\Local\Temp\TestRegistrationHandler3881105518\001/dra-plugin-a.sock:
bind: Only one usage of each socket address (protocol/network address/port) is normally permitted.

Creating unique socket path for every test case should fix it.
