Updated custom juniper paramiko

[dineshbaburam91]

• Updated juniper paramiko which supported aes128 and aes257 cipher.
• Fixed Python code style format running black tools

show system services
ssh {
ciphers [ aes128-gcm@openssh.com aes256-gcm@openssh.com ];
}

>>> from jnpr.junos import Device
>>> dev = Device(host='x.x.x.x', user='xxxx', password='xxxx')
>>> dev.open()
Device(x.x.x.x)
>>> dev.facts
{'2RE': False,
 'HOME': '/root',
 'RE0': {'last_reboot_reason': '0x4000:VJUNOS reboot',
         'mastership_state': 'master',
         'model': 'RE-QFX5110-48S-4C',
         'status': 'OK',
         'up_time': '384 days, 7 hours, 3 minutes, 29 seconds'},

Use updated paramiko (Juniper release) with additional support for aes128 and aes257 ciphers.
