Merge: + DHCP: Support statically configured leases 

Close #687

* commit 'b1fbd7c40c640eef575e6c2babc7eab26a525cf8':
  * openapi: add new dhcp methods
  * client: fix page scrolling on adding/deleting leases
  + client: handle static leases form
  + client: add table to show static leases
  + doc: DHCP static leases
  * dhcpd: refactor: use separate objects for ServerConfig and RWMutex
  + dhcp: /dhcp/status: return static leases
  * dhcpd: minor improvements
  * control: refactor: move DHCP lease -> json convertor to a separate function
  + dhcp: /dhcp/add_static_lease, /dhcp/remove_static_lease: control static lease table
  + helpers: parseIPv4()
  * control: use new DHCP functions: CheckConfig, Init, Start
  * control,dhcp: use dhcpServerConfigJSON struct
  + dhcpd: CheckConfig()
  * dhcpd: move code from Start() to Init()
