Update account and owner reserve

[alloynetworks]

Update defaults from 20/5 to 10/2 for account and owner reserves respectively. The network has been voting for 10/2 for an adequate period of time and a new server installation should default to the new reserves.

There should be no default vote in my opinion... the correct defaults are here: https://github.com/ripple/rippled/blob/8a25f3282426f382e1933242ef875d5aaf3e31e9/src/ripple/core/Config.h#L174-L175

Thanks for pointing this out. I didn’t realize it was in another location too.

I do agree with you that a hard coded default isn’t the best solution but I can’t think of how to ensure a non zero value without that.

Remove the default vote, leave in the default value and add a value representing the current fee structure on XRPL to the default config file since running rippled as a server for XRPL is likely the most common use case.
