feat: allow some services to be disabled by the end user as part of the installation

[w-le]

Most devs won't need these services:

influx
chronograf
mosquitto
source

and some like influx may be cpu/ram intensive.
Let's give an option for NOT installing and initializing those services, as part of the placeos start script.

I'll assign this to Rolando rdiaz after he joins place-labs

An approach like that of #49 can be taken here.

See docker compose profiles for more information

Oh sorry I only just saw that Caspian has already made this enhancement

I'll close this after #99 is merged, awesome change thanks caspiano
