Issue:
Incorrect documentation for CSWAP gate
<!-- ⚠️ If you do not respect this template, your issue will be closed -->
<!-- ⚠️ Make sure to browse the opened and closed issues -->

### Information

- **Qiskit Terra version**: 0.17.0
- **Python version**: 3.8.8
- **Operating system**: Windows 8.1

### What is the current behavior?
The documentation for CSWAP gate incorrectly mentions it as a controlled-X gate.


### Steps to reproduce the problem
See 
https://qiskit.org/documentation/stubs/qiskit.circuit.library.CSwapGate.html
and here as well:
https://qiskit.org/documentation/apidoc/circuit_library.html


### What is the expected behavior?
The documentation should say that it is the controlled swap gate.


### Suggested solutions
Update the appropriate docstring.




Discussion:
I will fix the typos, unless someone else has already been assigned to this.

Issue:
Bug in nakanishi_fujii_todo
<!-- ⚠️ If you do not respect this template, your issue will be closed -->
<!-- ⚠️ Make sure to browse the opened and closed issues -->

### Information

- **Qiskit Terra version**: 0.17.4
- **Python version**: 3.9.4
- **Operating system**: macOS Big Sur

### What is the current behavior?
nakanishi_fujii_todo() optimizer fail to return `OptimizeResult` except in the case of `args = ()`.


### Steps to reproduce the problem
I tried to run the following code 

```python

from qiskit.algorithms.optimizers.nft import nakanishi_fujii_todo
import numpy as np

def cost_function(param, a):
    return a[0] * np.sin(param) + a[1] * np.cos(param) + a[2]

a = np.random.rand(3)
nakanishi_fujii_todo(
    cost_function,
    x0 = [0.1],
    args = (a,),
    maxiter = 3
)

```

and then I got the following error

```python
TypeError                                 Traceback (most recent call last)
 in 
      3 
      4 a = np.random.rand(3)
----> 5 nakanishi_fujii_todo(
      6     cost_function,
      7     x0 = [0.1],

~/venv/lib/python3.9/site-packages/qiskit/algorithms/optimizers/nft.py in nakanishi_fujii_todo(fun, x0, args, maxiter, maxfev, reset_interval, eps, callback, **_)
    173                 break
    174 
--> 175     return OptimizeResult(fun=fun(np.copy(x0)), x=x0, nit=niter, nfev=funcalls, success=(niter > 1))

TypeError: cost_function() missing 1 required positional argument: 'a'
```

### What is the expected behavior?
nakanishi_fujii_todo() should return `OptimizeResult` without errors.


### Suggested solutions
`OptimizeResult(fun=fun(np.copy(x0)), x=x0, nit=niter, nfev=funcalls, success=(niter > 1))` should be `OptimizeResult(fun=fun(np.copy(x0), *args), x=x0, nit=niter, nfev=funcalls, success=(niter > 1))`

control_channels incorrect documentation in Pulse 
<!-- ⚠️ If you do not respect this template, your issue will be closed -->
<!-- ⚠️ Make sure to browse the opened and closed issues to confirm this idea does not exist. -->

### What is the expected enhancement?
From the [Pulse documentation](https://qiskit.org/documentation/apidoc/pulse.html#channels) on Channels, the method `control_channels(*qubits)` is defined as "Return `AcquireChannel` for `qubit` on the active builder backend." 

I expect the correct definition to be "Return `ControlChannel` for `qubit` on the active builder backend."

there's a `sort` argument in `plot_histogram()` which sorts according to the keys. But it would be useful to be able to sort according to the values (i.e. height of bars). Like put the most likely outcomes first and so on.

Issue:
Assigned pulse parameter is not converted into complex value.
<!-- ⚠️ If you do not respect this template, your issue will be closed -->
<!-- ⚠️ Make sure to browse the opened and closed issues -->

### Information

- **Qiskit Terra version**:
- **Python version**:
- **Operating system**:

### What is the current behavior?
This crashes execution because `ParameterExpression` is not JSON serializable.


### Steps to reproduce the problem

```python
from qiskit import pulse, circuit

amp = circuit.Parameter("amp")

with pulse.build() as sched:
    pulse.play(
        pulse.Drag(160, 1j * amp, 40, 0.1), 
        pulse.DriveChannel(0)
    )

sched.assign_parameters({amp: 0.5}, inplace=True)
sched.instructions[0][1].pulse.amp  # ParameterExpression(0.5*I)
```

### What is the expected behavior?

Assigned value should be converted into complex.


### Suggested solutions

Current format logic doesn't recognize `*I` as complex value.

### What is the expected behavior?
I have not seen this feature before, but if it does what it says,

https://qiskit.org/documentation/stubs/qiskit.compiler.transpile.html#qiskit-compiler-transpile

 I should be able to modify the duration of instructions.  Perhaps this is for pulses only, and the documentation just does not spell this out?


### Suggested solutions





Discussion:
This will be used if you specify a `scheduling_method`. I agree the docs should say this. 

Alternatively we make the passmanager take this info to mean scheduling is required. This is how e.g. coupling_map and basis_gates are used, even if you don't specify routing_method or translation_method. I think we should go with this.

Issue:
Define `__str__` for `Instruction` objects
### What is the expected enhancement?

Printing a `Instruction` to console shows the default pointer information because `__str__` is not defined. It would be useful to show at least the minimum information of the instruction itself, i.e. `self.name`, `self.num_qubits` and `self.num_clbits`.



Discussion:
@Lolcroc may I have a go at this?
Is the above-mentioned information sufficient for this `__str__` method? Also, if `self.name` is `None`, should there be any default name for an object instance?

Yes, a formatted string with just those parameters seems fine. If `self.name` is `None`, it makes sense to print it as `None`.
