Issue:
[ioctl] build contract invoke command line into new ioctl
### What would you like to be added
 - Step 1: create `contractinvoke.go` and `contractinvoke_test.go` files in `./ioctl/newcmd/contract`. create this directory if not exist. 
 - Step 2: refactor  command  https://github.com/iotexproject/iotex-core/blob/master/ioctl/cmd/contract/contractinvoke.go in `contractinvoke.go`
 - Step 3: add unit test in xx_test.go

#### Notes:
1. Use [client interface](https://github.com/iotexproject/iotex-core/blob/master/ioctl/client.go) to construct the Cobra command.
2. [Output package](https://github.com/iotexproject/iotex-core/blob/master/ioctl/output) is deprecated. `e.g.` `output.PrintError` could be replaced with `errors.Wrap`.
3. Global variables (config.ReadConfig  config.DefaultConfigFile etc.) have been wrapped into client interface. Please use [client interface](https://github.com/iotexproject/iotex-core/blob/master/ioctl/client.go) to access them if needed
4. The logic of new code should be similar to [the old one](https://github.com/iotexproject/iotex-core/blob/master/ioctl/cmd/contract/contractinvoke.go).
5. In each unit test, the results should be checked whether they are as the expected. 




#### Example:
1. https://github.com/iotexproject/iotex-core/blob/master/ioctl/newcmd/account/accountinfo.go
2. https://github.com/iotexproject/iotex-core/blob/master/ioctl/newcmd/account/accountdelete.go
3. https://github.com/iotexproject/iotex-core/blob/master/ioctl/newcmd/account/accountcreateadd.go

### Why is this needed
Unit tests couldn't be added for the old ioctl command (./ioctl/cmd) 


Pull request description:
[ioctl] Build contract invoke command line into new ioctl
# Description
Build `contractinvoke` command in new `ioctl`, with the following note.

* Use [client interface](https://github.com/iotexproject/iotex-core/blob/master/ioctl/client.go) to construct the Cobra command.
* Output package is deprecated, replace it with errors package.
* Replace fmt.Println with cmd.Println
* Refactor unit test to cover the modification.

Fixes #3309
