GEODE-7954: restore redundancy and status redundancy gfsh commands (#5004)
* GEODE-7954: restore redundancy and status redundancy gfsh commands
- Add redundancyStatus method to RestoreRedundancyOperation interface
- Add RestoreRedundancyCommand
- Add StatusRedundancyCommand
- Add RedundancyCommandFunction for use by the new commands
- Create RedundancyCommandUtils to hold shared code used by both
commands
- Unit and DUnit tests for all the above
Authored-by: Donal Evans <[email protected]>
* Addressing review comments
- Have the gfsh commands extend GfshCommand instead of SingleGfshCommand
- Remove unnecessary try/catch from RedundancyCommandFunction
Authored-by: Donal Evans <[email protected]>
* Fix LGTM alerts
Authored-by: Donal Evans <[email protected]>
* Applying review feedback
- Refactored tests to reduce code duplication
- Refactored to condense duplicated Restore and Status command code into
one class
- Refactored to condense unit tests for the above classes into one class

> Key: GEODE-7954
> URL: https://issues.apache.org/jira/browse/GEODE-7954
> Project: Geode
> Issue Type: New Feature
> Components: gfsh
> Reporter: Donal Evans
> Assignee: Donal Evans
> Priority: Major
>
> Add two gfsh commands to allow redundancy to be restored and to check the
> current redundancy status:
> {{restore redundancy [--include-region=value(,value)*]
> [--exclude-region=value(,value)*] [--reassign-primaries(=value)]}}
> {{status redundancy [--include-region=value(,value)*]
> [--exclude-region=value(,value)*]}}
> The first command will execute a function on members hosting the specified
> partitioned regions and trigger the restore redundancy operation for those
> regions, then report the final redundancy status of those regions.
> The command will return success status if:
> * Redundancy is fully satisfied for all regions that were included, either
> explicitly or implicitly.
> * No partitioned regions were found and none were explicitly included.
> The command will return error status if:
> * At least one bucket in a region has zero redundant copies, and that region
> has redundancy configured.
> At least one bucket in a region has fewer than the configured number of
> redundant copies.
> * At least one of the explicitly included partitioned regions is not found.
> * There is a member in the system with a version of Geode older than 1.13.0
> (assuming that is the version in which this feature is implemented).
> * The restore redundancy function encounters an exception.
> The second command will determine the current redundancy status for the
> specified regions and report it to the user.
> Both commands will take optional {{\-\-include-region}} and
> {{\-\-exclude-region}} arguments, similar to the existing rebalance command.
> If neither argument is specified, all regions will be included. Included
> regions will take precedence over excluded regions when both are specified.
> The restore redundancy command will also take an optional
> {{\-\-reassign-primaries}} argument to determine if primaries should be
> reassigned or not during the operation. The default behaviour will be to
> reassign primaries.
> Both commands will output a list of regions with zero redundant copies first
> (unless they are configured to have zero redundancy), then regions with less
> than their configured redundancy, then regions with full redundancy. The
> restore redundancy command will also output information about how many
> primaries were reassigned and how long that process took, similar to the
> existing rebalance command.
