Fix scheduler bugs

[Neylix]

Description

Fixes some bug on network transaction scheduler

• Add timeout on coingecko request to avoid node to not respond in time for transaction validation 8541abe
• Fix Process.exit on node detection which was not working with :normal reason 930a0ea
• Fix reward scheduler when receiving mint reward transaction while in scheduled state, expected behavior is to send node reward transaction after 51a91de
• Rework handling of node detection process when they exit 680abe8
• Update summary time and indexes after receiving oracle summary to avoid some cases when node do not pass in the aggregate handler 981f1ab
• Change date condition to send oracle summary transaction, in some case the polling_date may be greater than the summary_date, but the summary has not been sent. Now whenever the time is greater or equal to summary date, nodes send the summary transaction 981f1ab
