[improve][server] Support entryLogPerLedger, when dbStorage_directIOEntryLogger=true

[lordcheng10]

Motivation

When dbStorage_directIOEntryLogger=true, support for entryLogPerLedger.

Changes

1. Add a new DirectEntryLoggerForEntryLogPerLedger class extended from DirectEntryLogger;
2. In DbLedgerStorage, when building the EntryLogger object, judge whether entryLogPerLedgerEnabled is enabled:

 if (conf.isEntryLogPerLedgerEnabled()) {
                    entrylogger = new DirectEntryLoggerForEntryLogPerLedger(conf, ledgerDir,
                            new EntryLogIdsImpl(ledgerDirsManager, slog),
                            new NativeIOImpl(),
                            allocator, entryLoggerWriteExecutor, entryLoggerFlushExecutor,
                            conf.getEntryLogSizeLimit(),
                            conf.getNettyMaxFrameSizeBytes() - 500,
                            perDirectoryTotalWriteBufferSize,
                            perDirectoryTotalReadBufferSize,
                            readBufferSize,
                            numReadThreads,
                            maxFdCacheTimeSeconds,
                            slog, statsLogger);
                } else {
                    entrylogger = new DirectEntryLogger(ledgerDir, new EntryLogIdsImpl(ledgerDirsManager, slog),
                            new NativeIOImpl(),
                            allocator, entryLoggerWriteExecutor, entryLoggerFlushExecutor,
                            conf.getEntryLogSizeLimit(),
                            conf.getNettyMaxFrameSizeBytes() - 500,
                            perDirectoryTotalWriteBufferSize,
                            perDirectoryTotalReadBufferSize,
                            readBufferSize,
                            numReadThreads,
                            maxFdCacheTimeSeconds,
                            slog, statsLogger);
                }
