Forms need to show submit confirmation

[ayumi-b]

Issue: Upon entering and pressing 'submit', both apply and contact forms don't clear the fields and gives the user an impression that their entry didn't go through. This has caused many users to press submit multiple times --- and the slack collection to receive duplicate submissions. Possible Solution(s):

1. When the user presses 'submit', the message shows on the webapp that it's been received---that could be on a different page or at the same point.
2. Another option is if there could be an auto-generated email that is sent to the sender telling them that we got the message ---and the email gives them our contact email, or other information that may be of value to the sender. (e.g. joining our Linkedin community) This could be of value to the applicants who submit applications, and it would be an additional way to connect with them.
