Add Healthcheck Route #215

This is a route that connects to the database, connects to ldap, and returns a json blob stating whether or not it can connect.

This should allow us to more reasonably monitor on whether or not packet is up

How I want this to work

GET /api/v1/healthcheck

That would return 200 only when both ldap and the database connect correctly, and a 5XX range response when they don't. Different 5XX code for ldap down, sql down and both down

{
    "ldap": true,
    "database": true
}

Return the json no matter what the status code is.
Even better would be

{
    "ldap": {
        "status": true,
        "server": "stone.csh.rit.edu"
    },
    "database": {
        "status": true,
        "server": "mysql.csh.rit.edu"
    },
}
