KNOX-2940 - knoxcli create-alias/create-aliases command doesn't support values
starting with dash (#778)

> Key: KNOX-2940
> URL: https://issues.apache.org/jira/browse/KNOX-2940
> Project: Apache Knox
> Issue Type: Bug
> Components: KnoxCLI
> Reporter: Attila Magyar
> Assignee: Attila Magyar
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> If I want to create a password with a leading - character the create-alias
> command will fail:
> {code}
> knoxcli.sh create-alias name --value "-asdf"
> {code}
> The same is true for the batch alias creation command. Using quotes around
> the value doesn't help. Generated passwords sometimes contain - character and
> sometimes they start with that character.
> The reason for this is this check:
> {code}
> } else if (args[i].equals("--value")) {
> if (i + 1 >= args.length || args[i + 1].startsWith("-")) {
> printKnoxShellUsage();
> return -1;
> }
> {code}
> This tries to prevent incorrect usage by checking if the next parameter is
> likely an another command (so the actual value is missing).
> For example this prevents this case where the user mistakenly combined the
> --value (without defining a value) with the --generate command.
> {code}
> bin/knoxcli.sh create-alias test --value --generate
> {code}
> However we can prevent this by explicitly testing if the next parameter is
> any of the commands supported by the create-alias/create-aliases command.
> There are only 2, --generate and --cluster.
> So these kind of incorrect usages can be tested with:
> {code}
> if (args.length > i + 1 && ("--generate".equals(args[i + 1]) ||
> "--cluster".equals(args[i + 1]))) { // missing value
> printKnoxShellUsage();
> return -1;
> }
> {code}
> So I think we should use the above check instead.
> Misusing the batch alias command will generate error regardless of this check
> because the number of parameters won't match.
> Here there is no value for a1.
> {code}
> knoxcli.sh create-aliases --alias a1 --value --alias a2 --value v2
> {code}
> For this no extra check is required.
