No way to reuse an existing named DB connection

[abramyk-mv]

I try to run seed using an existing named DB connection and it does not work as expected.

To specify a connection name, I pass a connection property to configureConnection() function.
After digging in the code of the createConnection() function, I discovered that it is supposed to reuse a connection if it already exists.

typeorm-seeding/src/connection.ts

Lines 102 to 111 in 4136b0e

	if (connection === undefined) {
	try {
	connection = await TypeORMGetConnection(configureOption.name)
	} catch (_) {}
	if (connection === undefined) {
	connection = await TypeORMCreateConnection(ormConfig)
	}
	;(global as any)[KEY].connection = connection
	}
	return connection

So, the last step is calling a createConnection() function with configured above options.

But the issue is that this line of code never gonna work as expected.

typeorm-seeding/src/connection.ts

Line 104 in 4136b0e

connection = await TypeORMGetConnection(configureOption.name)

It retrieves a connection name from the name property of a configureOption object. The property is always undefined as it does not even exist in the ConfigureOption interface.

typeorm-seeding/src/connection.ts

Lines 17 to 21 in 4136b0e

	export interface ConfigureOption {
	root?: string
	configName?: string
	connection?: string
	}

I tried to change connection = await TypeORMGetConnection(configureOption.name) to connection = await TypeORMGetConnection(configureOption.connection) and it started to work properly.

Should I submit a PR for these changes or are there any restrictions I am not aware of?
