Set max daily upload limits

[Bosch-0]

Some users may have caps on their data usage (especially over cellular + during the IBD). A parameter you can set in Bitcoin Core is to limit max daily upload limits. Some things to consider:

• Use a snapshot (or assume UTXO) as to not use huge amounts of data of IBD - requires trust if snapshot source.
• Set a `-maxuploadtarget=
• Blocks only mode
• Disable listening
• Only sync over WiFi

I would suggest either:

1. Using a snapshot (or eventually assumeUTXO) for IBD with a max upload of ~144MB a day (enough to keep sync up to date daily) over cellular and no cap for WiFi connection.
2. Have IBD only sync over WiFi with no upload limit. Cellular upload limit of ~144MB a day set ONCE IBD is finished, no cap for WiFi.

We would definitely need an option in the settings menu of the application to set the maxuploadtarget, among other settings/options

I want to work on this. Could you please guide me on how to get this done?

We will not do the snapshot as discussed in #7, but adding a maxuploadtarget might be on the table, so I'll keep this open for now. I adjusted the labels from V1 to enhancement.

@jarolrod do you know if anything has been implemented related to maxuploadtarget?

assumeUTXO is covered in this issue.

Quick design mock for this feature (maxuploadtarget). What do you think, @jarolrod?
