add ztls fallback support

[tarunKoyalwar]

Please describe your feature request:

Since crypto/tls is strict and only allows limited amount of customization. which causes issues like e

• no renogotiation support in TLS 1.3 which causes local error: tls: no renegotiation nuclei#3553
• disables use of weak cipher suites which causes remote error: tls: insufficient security level nuclei#2805
  and others

we should use ztls as fallback when there are tls handshake related errors (as mentioned above)

Describe the use case of this feature:

• stability and more
• allows connection to outdated / legacy systems
