Use Dial with context

**What this PR does / why we need it**:
`net/http/Transport.Dial` field is deprecated:
```go
// DialContext specifies the dial function for creating unencrypted TCP connections.
// If DialContext is nil (and the deprecated Dial below is also nil),
// then the transport dials using package net.
DialContext func(ctx context.Context, network, addr string) (net.Conn, error)

// Dial specifies the dial function for creating unencrypted TCP connections.
//
// Deprecated: Use DialContext instead, which allows the transport
// to cancel dials as soon as they are no longer needed.
// If both are set, DialContext takes priority.
Dial func(network, addr string) (net.Conn, error)
```
This PR switches all `Dial` usages to `DialContext`. Fixes #63455.

**Release note**:
```release-note
HTTP transport now uses `context.Context` to cancel dial operations. k8s.io/client-go/transport/Config struct has been updated to accept a function with a `context.Context` parameter. This is a breaking change if you use this field in your code.
