Allow use of context (subdirectory) instead of subdomains

[muzzol]

Is your feature request related to a problem? Please describe.
Install script only gives you the option to use subdomains:

      api.mydomain.com
      mesh.mydomain.com
      rmm.mydomain.com

Describe the solution you'd like
I would like to use context instead of subdomains:

mydomain.com/api
mydomain.com/mesh
mydomain.com/rmm

Additional context
This configuration allows more options, simplicity and flexibility for certs, proxys and general management.
