plugins: Move install_requires into requirements.txt

We need to go through all the setup.py and setup_common.py for each plugin and take anything in the install_requires and move it to a requirements.txt file within the same directory. Then we need to modify setup_common.py (or setup.py if there is no setup_common.py) similar to how was done in 4867b4c1d6b1a51ef89e3926d0561a5502ad2850

REQUIREMENTS_TXT_PATH = Path(SELF_PATH, "requirements.txt")
if REQUIREMENTS_TXT_PATH.is_file():
    INSTALL_REQUIRES += list(
        map(lambda i: i.strip(), REQUIREMENTS_TXT_PATH.read_text().split("\n"))
    )

@SGeetansh, Go ahead and let us know if you need any help! Try following the first comment for one plugin and then move on to the others. A good starting point would be any of the model plugins 😃
