421a182f64 export metadata without nulls, empty arrays & default values ()
* export metadata without nulls, empty arrays
* property tests for 'ReplaceMetadata' using QuickCheck
-> Derive Arbitrary class for 'ReplaceMetadata' dependant types

* reduce property test cases number to 30
QuickCheck generates the `ReplaceMetadata` value really large
for higher number test cases. Encoded JSON for such values is large and
consumes more memory. Thus, CI is giving up while running property
tests.

* circle-ci: Add property tests as saperate job
* add no command mode to tests
* add yaml.v2 to go mod
* remove indirect comment for yaml.v2 dependency

9be6f706e6 Refactor GCtx to split query and mutation root operations
This mostly simplifies the RootFlds type to make it clearer what it’s
used for, but it has the convenient side-effect of preventing some
“impossible” cases using the type system.

5bafdce9a3 fix delete mutation returning incorrect data (fix ) (fix ) ()
From `alpha-40` we've been using a `WHERE` clause to fetch required rows and generate mutation response. This has a few limitations like the requirement of a primary key/unique constraint. This also returns inconsistent data on `delete` mutation as mentioned in . 
Now, we're using `VALUES (..)` (refer [here](https://www.postgresql.org/docs/current/sql-values.html)) expression to form virtual table rows in `SQL` to generate mutation response.

Internal changes:-
- Not to use primary key/unique constraint columns:-
  - Revert back to `ConstraintName` from `TableConstraint` in `TableInfo` type
  - Remove `tcCols` field in `TableConstraint` type
  - Modify `table_info.sql` and `fetchTableMeta` function `SQL`
- A test case to perform `delete` mutation and returning relational objects.

5f274b5527 fix mutation returning when relationships are present (fix ) ()
If returning field contains nested selections then mutation is performed in two steps
1. Mutation is performed with returning columns of any primary key and unique constraints
2. returning fields are queried on rows returned by selecting from table by filtering with column values returned in Step 1.

Since mutation takes two courses based on selecting relations in returning field, it is hard to maintain sequence of prepared arguments (PrepArg) generated while resolving returning field. So, we're using txtConverter instead of prepare to resolve mutation fields.
