Custom reloptions for table AM
Let table AM define custom reloptions for its tables. This allows specifying
AM-specific parameters by the WITH clause when creating a table.
The reloptions, which could be used outside of table AM, are now extracted
into the CommonRdOptions data structure. These options could be by decision
of table AM directly specified by a user or calculated in some way.
The new test module test_tam_options evaluates the ability to set up custom
reloptions and calculate fields of CommonRdOptions on their base.
The code may use some parts from prior work by Hao Wu.
