------------------------------------------------------
Commit 1767498 from [email protected] in branch 'vcl/trunk'
[ https://svn.apache.org/r1767498 ]
VCL-1000
Added to OS.pm:
* create_management_node_reservation_info_json_file
* delete_management_node_reservation_info_json_file
* get_management_node_reservation_info_json_file_path
* post_capture
* run_management_node_stage_scripts
Added call to run_management_node_stage_scripts in OS.pm::pre_capture. It only
gets executed if a 'enable_experimental_features' variable is true in the
database.
Added call to post_capture at the end of image.pm::process. It calls
run_management_node_stage_scripts which also only gets executed if a
'enable_experimental_features' variable is true in the database.

>
> There are cases where it would be useful to be able to have scripts executed
> on the management at various stages of reservations. For example, a script
> could be executed to configure an external firewall or provision storage when
> a computer is reserved. Whatever was configured specifically for the
> reservation could be reverted when the reservation ends by another script.
> We already have this functionality for scripts that get executed on the
> computer ([VCL-564|https://issues.apache.org/jira/browse/VCL-564]). However,
> there are situations where you would need to perform actions from the
> management node.
> The script would need access to information about the reservation. Since it
> resides and is executed on the management node, the script could call mysql
> to query the database. This isn't the safest way of handling things.
> Another option could be to create a text file on the management node prior to
> executing the script(s). The script could parse the text file to extract the
> information it requires.
