Fix adjacent slot range behavior in ASM operations (#14637)
This PR containts a few changes for ASM:

**Bug fix:** 
- Fixes an issue in ASM when adjacent slot ranges are provided in
CLUSTER MIGRATION IMPORT command (e.g. 0-10 11-100). ASM task keeps the
original slot ranges as given, but later the source node reconstructs
the slot ranges from the config update as a single range (e.g. 0-100).
This causes asmLookupTaskBySlotRangeArray() to fail to match the task,
and the source node incorrectly marks the ASM task as failed. Although
the migration completes successfully, the source node performs a
blocking trim operation for these keys, assuming the slot ownership
changed outside of an ASM operation. With this PR, redis merges adjacent
slot ranges in a slot range array to avoid this problem.
 
 **Other improvements:**
- Indicates imported/migrated key count in the log once asm operation is
completed.
 - Use error return value instead of assert in parseSlotRangesOrReply()
- Validate slot range array that is given by cluster implementation on
ASM_EVENT_IMPORT_START.

Redis Test Suite

The normal execution mode of the test suite involves starting and manipulating local redis-server instances, inspecting process state, log files, etc.

The test suite also supports execution against an external server, which is enabled using the --host and --port parameters. When executing against an external server, tests tagged external:skip are skipped.

There are additional runtime options that can further adjust the test suite to match different external server configurations:

Option Impact
--singledb Only use database 0, don't assume others are supported.
--ignore-encoding Skip all checks for specific encoding.
--ignore-digest Skip key value digest validations.
--cluster-mode Run in strict Redis Cluster compatibility mode.
--large-memory Enables tests that consume more than 100mb

Tags

Tags are applied to tests to classify them according to the subsystem they test, but also to indicate compatibility with different run modes and required capabilities.

Tags can be applied in different context levels:

  • start_server context
  • tags context that bundles several tests together
  • A single test context.

The following compatibility and capability tags are currently used:

Tag Indicates
external:skip Not compatible with external servers.
cluster:skip Not compatible with --cluster-mode.
large-memory Test that requires more than 100mb
tls:skip Not compatible with --tls.
tsan:skip Not compatible with running under thread sanitizer.
needs:repl Uses replication and needs to be able to SYNC from server.
needs:debug Uses the DEBUG command or other debugging focused commands (like OBJECT REFCOUNT).
needs:pfdebug Uses the PFDEBUG command.
needs:config-maxmemory Uses CONFIG SET to manipulate memory limit, eviction policies, etc.
needs:config-resetstat Uses CONFIG RESETSTAT to reset statistics.
needs:reset Uses RESET to reset client connections.
needs:save Uses SAVE or BGSAVE to create an RDB file.

When using an external server (--host and --port), filtering using the external:skip tags is done automatically.

When using --cluster-mode, filtering using the cluster:skip tag is done automatically.

When not using --large-memory, filtering using the largemem:skip tag is done automatically.

In addition, it is possible to specify additional configuration. For example, to run tests on a server that does not permit SYNC use:

./runtest --host <host> --port <port> --tags -needs:repl
