Split SecurityManagedConfiguration to mgmt and ddi starters (#2014)

* SecurityManagedConfiguration is moved to hawkbit-rest-core with commons for mgmt and ddi only
* Configurations for DDI and Management API are moved to respective starters
* hawkbit-http-security is removed - DosFilter (as common) is moved in hawkbit-rest-security, rest to the ddi starter as used only there
* some classes are moved into different packages - it is a bad practice to have same packet into multiple artifacts
