[DEVPLAT-6367] Add performance related configuration settings

[Neurostep]

Description

In this PR we are extending the Database configuration settings. Those configuration settings may help improving performance of the SQL operations in certain cases.

• DisableDefaultGormTransaction
  GORM performs write (create/update/delete) operations inside a transaction to ensure data consistency, which is bad for performance. It can be disabled with this setting to true

• CachePreparedStatements
  If set to true, creates a prepared statement when executing any SQL and caches them to speed up future calls.

• MysqlInterpolateParams
  If set to true, placeholders (?) in calls to db.Query() and db.Exec() are interpolated into a single query string with given parameters. This reduces the number of roundtrips, since the driver has to prepare a statement, execute it with given parameters and close the statement again with interpolateParams=false.

Note

Adds new DB performance settings and applies them to GORM (transactions/prepared statements) and MySQL DSN (interpolateParams), with tests and docs updated.

• Database:
  • Config (pkg/database/config.go): Add disable_default_gorm_transaction, cache_prepared_statements, mysql_interpolate_params.
  • Connection details (pkg/database/connection_details.go): Pass mysql_interpolate_params; include interpolateParams=true in DSN opts when enabled.
  • GORM init (pkg/database/gorm.go): Respect DisableDefaultGormTransaction (SkipDefaultTransaction) and CachePreparedStatements (PrepareStmt).
• Tests:
  • Update config_test.go and connection_details_test.go to assert new config fields and DSN option.
• Docs:
  • Expand README database settings table with the new options.
