Bug 1049608

+++ This bug was initially created as a clone of Bug #1020066 +++

Description of problem:
Executing a script server resource with an argument string including a quoted argument that contains spaces results in the quoted argument being broken out into multiple arguments.

For example, "a b" is treated as two arguments.  '"a' is the first argument, and 'b"' is the second.

Version-Release number of selected component (if applicable):
JBoss ON 3.1.2

How reproducible:
very

Steps to Reproduce:
1. Import script server resource (script example below)
2. Perform "Execute" operation on script server resource
3. Input arguments "a b"
4. Verify output

testScript.sh contents:
#!/bin/sh

echo $# number of arguments > output.txt
echo $* >> output.txt
echo $@ >> output.txt


Actual results:
Script reports that 2 arguments have been passed into it.

Expected results:
Script should report that 1 argument was passed in.

This issue is a direct result of how the operation's arguments property value is passed along to executeExecutable and then split into multiple arguments using the space:

    https://git.fedorahosted.org/cgit/rhq/rhq.git/tree/modules/plugins/script/src/main/java/org/rhq/plugins/script/ScriptServerComponent.java#n405

The end result is that:
    Arg1 "Arg 2" Arg3

Becomes:
    Arg1
    "Arg
    2"
    Arg3

And:
    Arg1 'Arg 2' Arg3

Becomes:
    Arg1
    'Arg
    2'
    Arg3

And:
    Arg1 Arg\ 2 Arg3

Becomes:
    Arg1
    Arg\
    2
    Arg3


To fix this, a more suitable regular expression and matcher should be applied to handle quoted (double or single) parameters and/or escapes. Possibly a simple command-line parser?

The most basic form is to support:

Arg1 "Arg 2" Arg3
Arg1 'Arg 2' Arg3

However, from a command-line perspective, the quote may need to be escaped:

Arg1 'Arg\'s 2 Value' Arg3

Additionally, the following format seems to be common within the Linux realm:

Arg1 Arg\ 2 Arg3
