Igniteui-angular: Feature request: Using text field input for date and time picker

[Eralmidia]

Description

When using the date and time picker, it seems it is currently only possible to use the popup to select a date. Both controls should support keyboard inputs as well, similar to https://eonasdan.github.io/bootstrap-datetimepicker/ for instance.

We already had planned to implement this. This is the spec for the time picker:
https://github.com/IgniteUI/igniteui-angular/wiki/Time-Picker

I've created a new issue to implement input for date picker. - #3034

We will implement input for time picker only in this issue as it's already described in the time picker specification.

With this issue we will implement new mode - input + drowdown. In addition the component will be migrated from dialog to overlay. See the spec for more details.
