CommandObjects refactoring Part 4: Backport deprecations to 7.5.x

[uglide]

Note

Medium Risk
Enables HTTPS-style hostname verification by default for TLS sockets and changes cluster pipelining execution semantics, which can break existing deployments relying on permissive TLS or implicit executor lifecycle.

Overview
Bumps project version to 7.5.0-SNAPSHOT and continues the CommandObjects refactor by deprecating the no-arg constructors and setProtocol, steering callers to constructor-injected RedisProtocol (also deprecating AbstractClientBuilder.applyCommandObjectsConfiguration).

Adds opt-in support for shared ExecutorService usage in cluster pipelining: JedisCluster/RedisClusterClient gain pipelined(ExecutorService) and MultiNodePipelineBase now reuses a provided executor instead of always creating/shutting down its own; new tests cover shared-executor concurrency and lifecycle.

Hardens TLS behavior by defaulting DefaultJedisSocketFactory to enable hostname verification (SSLParameters endpoint identification HTTPS) when no custom parameters are provided, and expands TLS integration tests/endpoints to validate failure on wrong-host certificates and the ability to disable verification via custom SSLParameters.
