Provide support for gMSA in Bamboo Windows service

What is a Group Managed Service Account (gMSA)?

Group Managed Service accounts are perfect identity solutions for services running on multiple hosts. Password management requires no administration overhead as password management is handled automatically using Windows Server 2012 and later versions across multiple hosts. It also supports offline hosts that are not connected to the network for a period of time, and when they go back online, the password is synchronized on the service running on them, so that the service can start successfully.
