GEODE-3092: fix specifiedDefaultValue for cacheLoader and cacheWriter
(cherry picked from commit c6d88f7)
> Using the gfsh alter region command to unset a CacheWriter no longer works
> --------------------------------------------------------------------------
>
> Key: GEODE-3092
> URL: https://issues.apache.org/jira/browse/GEODE-3092
> Project: Geode
> Issue Type: Bug
> Components: gfsh
> Reporter: Barry Oglesby
> Assignee: Jinmei Liao

> In 1.1, a command like this is used to unset the CacheWriter:
> {noformat}
> gfsh>alter region --name=/Person --cache-writer=''
> Member | Status
> ------- | -------------------------------------
> server1 | Region "/Person" altered on "server1"
> {noformat}
> In 1.2, that same command fails:
> {noformat}
> gfsh>alter region --name=/Person --cache-writer=''
> Member | Status
> ------- | ----------------------------------------------------------------
> server1 | ERROR: Could not find class "null" specified for "cache-writer".
> {noformat}
> And throws this RuntimeException on the server:
> {noformat}

> @CliOption(key = CliStrings.ALTER_REGION__CACHEWRITER,
> unspecifiedDefaultValue = CliMetaData.ANNOTATION_NULL_VALUE,
> specifiedDefaultValue = "null",
> help = CliStrings.ALTER_REGION__CACHEWRITER__HELP) String
> cacheWriter,
> {noformat}
> To:
> {noformat}
> @CliOption(key = CliStrings.ALTER_REGION__CACHEWRITER, specifiedDefaultValue
> = "null",
> help = CliStrings.ALTER_REGION__CACHEWRITER__HELP) String
> cacheWriter,
> {noformat}
> What is passed to the RegionAlterFunction now is a string with the value
> "null".
> I think the same issue exists for the CacheLoader.
