[Elephant] Refactoring on MosaicDefinitionTransaction

[rg911]

Based on recent catbuffer mosaic definition schema changes

1. mosaicProperties has been made deprecated and split into 3 fields in mosaic definition: flags, divisibility and duration
2. duration is required now. Providing 0 value for specifying eternal mosaic.
3. Also means propertyCount and IndicateDuration get dropped from the transaction payload.

Proposed work:

• Remove mosaic property
• Refactoring mosaic definition transaction builder (should use the new ts catbuffer code)
• Testing
