Name resolver & new search bar

[JulienPeloton]

Introduce a name resolver. Names will be resolved in 3 different ways:

1. using SIMBAD (Sesame service)
2. using SSODNET (for small bodies)
3. using TNS (for extra-galactic transients)

For all, there will also be a reverse resolver, that is given a ZTF objectId, what is the match in these catalogs. Note that SSODNET and TNS allow auto-completion, but not SIMBAD.

Todo:

• Add a new endpoint (Name resolver #484)
• API documentation (in the form of howto)
• Update the main page to allow conesearch by name
• Add a page for autocompletion test (where coordinates can be copied for example)
