GRR v3.4.2.4 with fleetspeak installation

**Environment**
- How did you install GRR? [e.g. from release DEB, HEAD DEB, PIP package, source]
With instructions from https://grr-doc.readthedocs.io/en/latest/installing-grr-server/from-release-deb.html

- What GRR version are you running?: [e.g. 3.1.2.3]
v3.4.2.4
- What operating system does the GRR server run on? [e.g. Ubuntu 18.04]
Ubuntu 18.04
- What operating system does the affected GRR client run on, if applicable? [e.g. Windows 10]
No Windows 32bit client binaries were found. I need windows 32 bit client to be packed.

**Describe the issue**

I managed to install via DEB and it works perfectly. But issues here is that there is no 32bit Windows client in the UI. Only 64bit is visible. I found out that we need to build a custom template as what is written here
: https://grr-doc.readthedocs.io/en/v3.4.2.4/maintaining-and-tuning/building-custom-client-templates.html

The issues is that upon building it, it seems like no fleetspeak and no mysql account found for fleetspeak (In this case mysql has been install for GRR only and not fleetspeak)

I believe when we use .DEB installation, it will ask us whether to use Fleetspeak Experimental, if we choose Y, we have to specify the information. What to be submitted here anyway?

The objective here,

how can i get them install with my initial installation with .DEB ?? I really need windows 32 bit binary client and not just 64 bit.

Thanks in advance.
