Add a job page for companies

[anistark]

With increasing interest towards hiring and to help companies reach out to python developers to hire, we would want a job page where companies can list their openings.

As discussed:

• This job page is only for companies to list openings.
• Candidates can connect with BangPypers volunteers and the volunteers can connect offline to the companies.

Queries:

• Should this jobs listing be made public?
• What info should be made public and what should not?

Until we can reach a decision on the above queries, this will be only for the volunteers eyes only.

For now, need to insert the below content to have this page live:

Automatically adjust height to fit the form's content
