Functional Cargo test --workspace

[phexyz]

1. In integration.rs tests are ran after the the reth binary are brought up

2. Made a minor change for

3. Fixed backup datadir bug. This was causing failure with inconsistent datadir recognized by the Backup handle (which was instantiated in TreeConfig) vs the real Datadir from LaunchContext

4. Update seismic.yml to use the updated set of test

5. update the sync_to time to 30s upperbound from the orginal 10s. The current time it takes for e2e_test_send_transaction is 17s on large runner

6. upgrate seismic.yml to use cargo nextest to increase test speed

7. These tests still fail if you run on upstream reth locally on mac against this commit so not sure how they succeed in github actions. We ignore them in .config/nextest.toml

eth::core::tests::* --exact --show-output to reproduce
cargo test --package reth-rpc --lib --all-features -- eth::core::tests --exact --show-output

This failure is due to the fact that BaseFeeParams calculates next_block_base_fee differently from BaseFeeParams. See temporary fix here commit

providers::static_file::tests::test_header_truncation and providers::static_file::tests::test_tx_based_truncation to reproduce
cargo test --package reth-rpc --lib --all-features -- providers::static_file::tests::test_header_truncation
