Description

Removed redundant methods capabilities and set_capability in wpewebkit/options.py
Since Options class in wpewebkit/options.py inherits from ArgOptions, I have removed redundant methods which sets and gets capabilities.

Replaced set_capabilities method with a setter method to add capabilities to self._caps.

Motivation and Context

Since both methods capabilities and set_capability are already implemented in parent class
selenium.webdriver.common.options.ArgOptions, I found that same attributes are being implemented once again in wpewebkit/options.py.

To get the capabilities from internal dictionary self._caps we do have a getter method in
selenium.webdriver.common.options.Options class

@property
def capabilities(self):
return _caps

And the capabilities are being set through set_capabilities method. For the purpose of consistency I have
repalced set_capabilities() method in selenium.webdriver.common.options.Options class to a setter method.

@property.setter
def capabilities(self, values):
name, value = values
self._caps[name] = value

so now the capabilities can be set through setter,

self.capabilities = ("pageLoadStrategy", "normal")
