Make sure AR Trilogy adpater does not modify input

[miry]

During working with Trilogy adapter,
found that semian key removed from the original Hash.

Update adapter to use copy of input structure, instead of modify the object it self.

Example how to reproduce the problem:

SEMIAN_PARAMETERS = {
  circuit_breaker: true,
  success_threshold: 1,
  error_threshold: 3,
  error_timeout: 3,
  bulkhead: false,
}

configuration = {
  adapter: "trilogy",
  username: "root",
  host: ENV.fetch("MYSQL_HOST", "localhost"),
  port: Integer(ENV.fetch("MYSQL_PORT", 3306)),
  database: "mysql",
  semian: SEMIAN_PARAMETERS,
}

adapter = ActiveRecord::ConnectionAdapters::TrilogyAdapter.new(configuration)
adapter.execute("SELECT 1;")

adapter = ActiveRecord::ConnectionAdapters::TrilogyAdapter.new(configuration)
adapter.execute("SELECT 1;")
# Print in logs that Semian is not configured
