[SPARK-50397][CORE] Remove deprecated --ip and -i arguments from Master/Worker

[dongjoon-hyun]

What changes were proposed in this pull request?

This PR aims to remove --ip and -i arguments from Master/Worker from Apache Spark 4.0.0.

Why are the changes needed?

These arguments were deprecated on Apr 15, 2013 before v0.8.0-incubating and have never been used in Apache Spark code base.

Utils.checkHost(value, "ip no longer supported, please use hostname " + value)

Does this PR introduce any user-facing change?

Yes, however, I believe these incubating-era arguments are not only misleading (because IPs are not hostnames) but also not required in Apache Spark 4.0.0 users.

How was this patch tested?

Manual review.

To @mridulm , I saw that these were deprecated by you at 0.8.0-incubating.
It's over 10 years and probably I believe we can let them go from Apache Spark 4.0.0. WDYT?

[dongjoon-hyun]

All tests passed.
