CASMINST-7104 : passing image and config for rebuild

[Pankhuri-Rajesh]

Description

Adding a check for "cfs_config" and "ims_image" in rebuild task. If the parameters were passed , use them to rebuild the node rather than prepare-images output. If not passed workflow will use prepare-images output as it currently does.

Added a new task called "rebuild-config-image-update" in all the management rollouts templates which updates the activity configmap with the image and cfs configuration used. This is a conditional step, and is executed only if the parameters are not empty strings. (implemented using "when" key)

Also the documentation changes for the new feature updated in markdown files .

Testing:

Tested without rebuilding the nodes. Needs to be tested with rebuild once cluster is available
