[xcvrd] Introduce regex style keys in media_settings for setting up port configuration in xcvrd

[vdahiya12]

Description

This PR introduces a new way of specifying keys in media_settings file in a regex format. This way port settings will be applied to ports specified in GLOBAL_MEDIA_PATTERN_SETTINGS key in the media_settings.json key and whichever port vendor key matches the regex format key, they will be configured with params specified for that key.
If None of the keys match, default settings if any will be applied as in GLOBAL_MEDIA_SETTINGS or PORT_MEDIA_SETTINGS.

{
    "GLOBAL_MEDIA_PATTERN_SETTINGS": {
        "1-32": {
            "^QSFP28+\\.*10G.*SR.*": {
                   "interface_type": "sr4"

            },
            "^QSFP\\+.*40G.*": {
                   "interface_type": "sr4"

            },
            "QSFP\\+.*100GBASE-LR4.*": {
                   "interface_type": "sr4"

            }

        }
    }
}

@vdahiya12 dkey = "^QSFP28+\.*10G.SR.", then the return should be media_dict["^QSFP28+\.*10G.SR."]
need to return media_dict[dkey] ?

hi @keboliu @Junchao-Mellanox can you review the change ?

[StormLiangMS]

hi @vdahiya12 this one more like an enhancement, what's the justification to have this into 202305?

[lguohan]

we should not accept this into 202305, @vdahiya12 , as we discussed, please do not backport this into 202305.

[vdahiya12]

as discussed will add in master for now
