Split yggdrasilctl code into separate functions (refactoring) (#815)

Browse Source 
* Move yggdrasilctl responses to separate functions

* Move yggdrasilctl request switch to separate function

* Add empty lines

* Create struct CmdLine for yggdrasilctl

* Move yggdrasilctl command line parsing to separate func

* Turn struct CmdLine into CmdLineEnv

* Rename func parseCmdLine to parseFlagsAndArgs

* Move yggdrasilctl endpoint setting logic into separate func

* Function to create yggdrasilctl CmdLineEnv

* Reorder code

* Move struct fields into lines

* Turn yggdrasilctl CmdLineEnv funcs to methods

* Move yggdrasilctl connection code to separate func

* Rename functions

* Move yggdrasilctl command line env to separate mod

* Move yggdrasilctl command line env to main mod

* Run goimports
