What changes were proposed in this pull request?

ServerNotLeaderException carries the SCM suggested-leader address in its message. The IPv6 fast path was broken because:

  1. The server produced ambiguous authorities such as 2001:db8::1:9863.
  2. The client-side parser rejected IPv6 hosts.
  3. The failover proxy compared address strings, so equivalent compressed and expanded IPv6 forms could differ.

This patch:

  • Formats IPv6 authorities as [2001:db8::1]:9863.
  • Extends the exception parser to accept bracketed IPv6.
  • Matches the hint against cached SCM addresses without DNS lookup.
  • Compares IP literals canonically while preserving IPv6 scope IDs.
  • Logs malformed hints and falls back to round-robin failover.

Matching avoids DNS because performFailoverToAssignedLeader holds the provider monitor. Consequently, aliases that require a new lookup to prove equivalence may use round-robin instead. This affects only the fast path, not failover correctness.

During rolling upgrades, old clients cannot parse the new bracketed IPv6 format. However, they also could not parse the old ambiguous IPv6 format, so existing behavior is unchanged until both sides contain the patch. Hostname and IPv4 message formats remain unchanged.

What is the link to the Apache JIRA?

https://issues.apache.org/jira/browse/HDDS-15895

How was this patch tested?

Added coverage for:

  • IPv6 exception conversion and RPC message parsing.
  • Compressed versus expanded IPv6 addresses.
  • IPv6 scope ID handling.
  • A hostname-configured SCM matched by its cached IP.
  • IPv4 and unresolved-hostname regression paths.
  • Malformed hints falling back to round-robin.

HDDS-15895. Match suggested leader without resolving addresses
ad61a5f 
Compare the suggested-leader authority against the cached SCM addresses using host
text only, so the IPv6 scope is honoured and no name lookup runs while the provider
monitor is held.

InetSocketAddress.equals compares only the address bytes, so [fe80::1%1] and
[fe80::1%2] matched each other and failover could pin the wrong SCM. Both the
resolved-address comparison and the NetUtils.getHostPortString call it replaced
could also resolve inside the synchronized failover path.

Matching now reads getHostString() and the already resolved getAddress(), and
normalizes IP literals through Guava InetAddresses so compressed and expanded IPv6
forms match. A hint that carries a name the cached entry never resolved to no longer
matches; such a hint falls back to round-robin failover as before.

Thanks for the review! @smengcl I addressed both comments and added regression tests.

HDDS-15895. Compare IPv6 zone names case-sensitively
b7390ab 
equalsIgnoreCase short-circuited before sameIpLiteral, so a %eth0 suggested-leader hint
matched a %ETH0 SCM. Interface names are case-sensitive, so failover could pin the wrong
node, the same class of bug the scope-id comparison already fixed.

Host matching now routes IP literals to sameIpLiteral and keeps case-insensitive matching
for hostnames only, where DNS requires it.
