netbox in subfolder: api search is not working for tags

[lwillek]

Environment

• Python version: 2.7.16rc1
• NetBox version: 2.5.8

If you install netbox as usual, but configure a subfolder like https://mydomain.org/netbox to access your installation, then you have to set the BASE_PATH in configuration.py and nearly everything works like a charm.

Unfortunately working with tags is difficult, because the Ajax results could not be loaded if you try to search or modify tags with help of the ui.
The reason is that within the static javascript, the var netbox_api_path is not used. Instead, the api url is hardcoded: https://github.com/digitalocean/netbox/blob/develop/netbox/project-static/js/forms.js#L253

The solution is easy: just use the variable, i.e url: netbox_api_path + 'extras/tags/', instead of url: "/api/extras/tags/",

A quick workaround without adapting the code is to rewrite the incoming requests. For Apache this config will do the job:

        RewriteEngine  on
        RewriteRule    ^/api/(.*)      /netbox/api/$1 [R=permanent]

I will write a small patch to avoid the "rewrite" workaround.

Thanks for this. I noticed you opened a PR in your fork with the fix, would you mind opening one here?
