Parse inspected console item definition

[maksym-nazarenko]

This PR allows to generate MikroTik resource with list of all fields, which are available in RouterOS. Detailed description is available in README.

Example of generated dhcp-server resource.

$ go run cmd/mikrotik-codegen/main.go mikrotik -commandBase /ip/dhcp-server -name DhcpServer -inspect-definition-file ./inspect_definition.txt

or fully automated way of querying remote system for the fields list:

$ go run cmd/mikrotik-codegen/main.go mikrotik -commandBase /ip/dhcp-server -name DhcpServer -query-definition

show output

```go type DhcpServer struct { Id string `mikrotik:".id"` AddArp string `mikrotik:"add-arp"` AddressPool string `mikrotik:"address-pool"` AllowDualStackQueue string `mikrotik:"allow-dual-stack-queue"` AlwaysBroadcast string `mikrotik:"always-broadcast"` Authoritative string `mikrotik:"authoritative"` BootpLeaseTime string `mikrotik:"bootp-lease-time"` BootpSupport string `mikrotik:"bootp-support"` ClientMacLimit string `mikrotik:"client-mac-limit"` Comment string `mikrotik:"comment"` ConflictDetection string `mikrotik:"conflict-detection"` CopyFrom string `mikrotik:"copy-from"` DelayThreshold string `mikrotik:"delay-threshold"` DhcpOptionSet string `mikrotik:"dhcp-option-set"` Disabled string `mikrotik:"disabled"` InsertQueueBefore string `mikrotik:"insert-queue-before"` Interface string `mikrotik:"interface"` LeaseScript string `mikrotik:"lease-script"` LeaseTime string `mikrotik:"lease-time"` Name string `mikrotik:"name"` ParentQueue string `mikrotik:"parent-queue"` Relay string `mikrotik:"relay"` ServerAddress string `mikrotik:"server-address"` UseFramedAsClassless string `mikrotik:"use-framed-as-classless"` UseRadius string `mikrotik:"use-radius"` } ```

Sorry for the extremely late review on this. Very exciting to see the code generation pieces coming together!
