Jenkins controller: Increase jenkins home disk size

[mkaapu]

This is workaround to allow more build records to be stored on Jenkins home directory.

My suggestion to continuation work:

Separate store for Jenkins workspace

• for proper CI control / build isolation, Jenkins master node should have 0 executors and all working directories should reside in agent machines.

Separate jobs configuration, build records and artifacts from Jenkins home

• one solution: symbolic links to another store
• build artifacts may needs some more persistent store separate from other build records

This is needed to enable changes in CI pipeline:

I just checked @flokli comment and looks like we need to enable the azure Storage plugin on Jenkins then Configure the plugin with the Azure storage...
