[stork-users] lease Search

[Slawek Figiel]

Hello Ralf!

The API is called in line 161:

```
         this.dhcpApi
             .getLeases(searchText)
```

The UI API client is generated by the OpenAPI Generator, and its 
requests are handled by the API generated by GoSwagger. The API is 
defined in the /api directory.

The "getLeases" UI call executes the "GetLeases" handler in the backend 
code (backend/server/restservice/leases.go:23).

The "GetLeases" handler calls the "FindLeases," "FindDeclinedLeases," 
and "FindLeasesByHostID" functions defined in the 
backend/server/apps/kea/lease.go file. These functions prepare and send 
the requests to the Stork agent through the 
"agents.ForwardToKeaOverHTTP" calls.

The requests are received by the handler implemented in 
"backend/agent/agent.go:367" and then passed throught to Kea API by the 
"sa.KeaHTTPClient.Call" call (line 396).

The search filter value is set in 
"webui/src/app/lease-search-page/lease-search-page.component.ts" in line 
149. It is bound to the text input with the "leases-search-input" ID 
defined in 
"webui/src/app/lease-search-page/lease-search-page.component.html:21".

I hope it will be helpful for you!

Regards,
Slawek Figiel
