9x backport for "SOLR-7962 --jvm-opts with -e doesn't work on windows (#3347)"

[rahulgoswami]

https://issues.apache.org/jira/browse/SOLR-7962

Description

• solr.cmd wasn't passing additional arguments to SolrCLI when running an example (-e option)
• Parsing of the prepared command line in RunExampleTool was breaking due to certain characters in the additional args. Eg: -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:18983". commons-cli had to be "signaled" to ask cmd.exe to preserve the quotes while passing to start.cmd
• If an additional arg (supplied with "--jvm-opts") starts with "-D", the parsing breaks.

Solution

• Pass additional args to SolrCLI when running with -e
• Parse the command in RunExampleTool without the additional args to prepare excec.CommandLine and then add the addtional args separately with quotes preserved.
• If a system property (-D) is passed as an additional argument with --jvm-opts, pass it along to the RunExampleTool, unlike the other -D arguments.

Tests

Added bats test for jvm-opts with example
