You do not need this API method. Migrate is defined as an action so you can call element_action(ID, "migrate", ...)

Regular users should not be allowed to migrate elements, so there should be an admin check

- removed unnecessary api call for migration - changed action_migrate to try_migrate - there is no host parameter anymore - the element searches for a new host and migrates if necessary - changed checkForHostDeactivation - now it checks every 5 minutes if the system can handle the load of a host - it sets a fixedPref which affects the value of the host - renamed host_management to dynamic_allocation - it checks periodic if the system can allocate or detache hosts
…cation and deactivation to config.py Fixed some bugs for different elements by updating the try_migration function. Made some changes and name changes in host.py: * changed checkHostDeactivation to loadInfluencer * updated load influencer * updated getBestHost * changed getHostValue to getHostScore * updated getHostScore * changed hostReallocation to migrator * added the migrator as an periodic function beeing activated every 30 min.
