[apim][portal] Replace select by autcomplete in contact form

[gcusnieux]

:rainbow: Feature

As a 'Portal user'

I want to 'use an autocomplete to find api or applications in contact page'

So that 'select loads all apis and applications'

:sunrise_over_mountains: Additional information

This will improve two things:

• usability (to find the concerned api)
• performance (data loading will be faster)

Technically, beyond the UI, we must use the search /apis/_search?q=My api and not use /apis?size=-1. By the way, we should remove the size=-1 behavior on /apis and have only paged results. This degrades the performance See the benchmark https://github.com/gravitee-io/gravitee-api-management/pull/938

For the /apis/_search we could transform the HTTP method from POST to GET, the POST method brings nothing.
