0019895: CPU spike during invoice header click

DescriptionWhen opening the invoice tab in grid mode I navigate to click a record in the grid which then results in CPU utilization spikes of 10-30%. The result of this in a concurrent scenario would be that multiples of 5-10 users will exhaust the CPU.
Steps To ReproduceSee above
Proposed SolutionLooked at the FIC component and currently focusing on the computevalues area which appears to cause the CPU overhead
TagsNo tags attached.

Fixed issue 19895. Done several changes to improve the performance of the FIC and reduce the server load (specially when the user selects a record in grid):
- Cached the whole Tab instance in the FIC (not only its related objects (fields, auxiliary inputs, ...)) to avoid an additional (and expensive) query
- Removed the OBCriteria for the attachments and notes. They've been replaced by an OBQuery and a HQL Query to reduce computation time.
- Replaced the UsageAudit call in each DataSourceServlet request by the non-dal version (which greatly reduces the computation cost)
- Added a constructor in the DynamicExpressionParser class so that an instance of ApplicationDictionaryCachedStructures can be passed if it is available. This avoids having to do an expensive call to Weld when the FIC uses the DynamicExpressionParser.
