Upload Profile Picture option for users in EditProfile

## Description
As a user of the Android app,
I need to be able to upload a profile picture,
so that I can complete my user profile.

Taken from this [Google Code in task](https://codein.withgoogle.com/tasks/4959726316552192/)

> As a user of the application , if I click on "Profile" option from Bottom Navigation "My Profile " screen opens up . On clicking "edit icon" 🖋 (at right top) an alert dialogue box named "Edit Profile" opens up . In the dialogue box , there is no option of uploading profile picture .

> Your task is to only design "upload profile picture option" so that user of the application can later on upload his/her picture in Edit Profile Section of the application. e.g you can use a camera icon or design something beautiful and innovative accordingly.
The user should be able to upload a local image to the Android app.
