Add Healthcheck Route

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
```json
{
"ldap": true,
"database": true
}
```
Return the json no matter what the status code is.
Even better would be
```json
{
"ldap": {
"status": true,
"server": "stone.csh.rit.edu"
},
"database": {
"status": true,
"server": "mysql.csh.rit.edu"
},
}
```
